Cypress Semiconductor has introduced the industry’s first quad-PLL (phase-locked loop) timing device with a two-wire I2C programming interface.

Cypress Semiconductor has introduced the industry’s first quad-PLL (phase-locked loop) timing device with a two-wire I2C programming interface. The I2C programming allows manufacturers to reduce time to market by programming frequencies on the printed circuit board instead of having to order factory-programmed parts or use an additional manufacturing step. It also allows customers to order one part number and use it for multiple products and design iterations, reducing inventory requirements.

The new CY24488 meets critical timing requirements in digital set-top boxes, DVD recorders, digital TVs and other complex systems requiring synthesis of multiple, unrelated frequencies.

The CY24488 replaces multiple crystals, reducing BOM (bill of materials) cost.

It provides three independent frequencies and one buffered reference frequency.

The programmable output frequencies range from 4.9152 to 148.5MHz, compatible with most digital entertainment devices.

The device has an integrated analogue voltage controlled crystal oscillator (VCXO) with a minimum pull range of +/-120ppm for maximum frequency resolution and better frequency tracking.

It also includes programmable output drive strength for EMI control and a 2.5V option to interface with lower voltage ICs without extra circuitry.

‘As our recent design win with Hitachi shows, we offer superior timing solutions for the digital entertainment market’, said Wayne Gill, Managing Director of Cypress’s General-Purpose Clock Business Unit.

‘The addition of I2C programming gives customers another reason to choose Cypress for these applications’.

NDK has developed the first commercially available 4MHz thickness shear vibration mode (AT-cut) SMD crystal unit, in a small 8.0 x 4.5 x 1.8mm package.

NDK has developed the first commercially available 4MHz thickness shear vibration mode (AT-cut) SMD crystal unit, in a small 8.0 x 4.5 x 1.8mm package, the NX8045GB series. This low frequency was previously only available in larger packages like the NX1225GB (11.8 x 5.5 x 2.5mm). The NX8045GB offers a reduction in volume of nearly 60% (65mm3 compared with 162mm3).

The low frequency operation keeps the power consumption low (drive level 50uW) and can be applied with existing IC designs.

It is available in a frequency range of 4-40MHz with a frequency tolerance of +/-30ppm at an ambient temperature of +25C.

The NX8045GB is ideal for automotive applications with an operating temperature range of -40 to +125C, delivering superior environmental performance including high heat, vibration and impact resistance.

Maximum equivalent resistance is 280ohm and frequency stability is +/-180ppm (from -40 to +125C).

The NX8045GB meets the requirements for reflow profiling using lead-free solder, and is RoHS compliant.

‘The automotive electronics industry is pursuing lighter, more compact, power saving devices’.

‘NDK’s miniaturisation design techniques used in the NX8045GB enables us to deliver high volume production without compromising the superior characteristics delivered by thickness shear vibration mode crystal units’, said Mike Walczak, President, NDK America.

Delivery for the NX8045GB series is 12 weeks ARO.

Cost for 10,000 pieces of the NX8045GB packaged tape and reel is approximately US $0.46 each.

Qualified engineering samples may be ordered at no cost.

Clock IC combines low phase noise clock generation with 14-channel clock distribution at jitter levels below 1ps.

Analog Devices is introducing the industry’s first clock IC to combine low phase noise clock generation with 14-channel clock distribution at jitter levels below 1ps. The AD9516 series integrates an integer-N synthesiser, two reference inputs, a voltage-controlled oscillator (VCO), programmable dividers, adjustable delay lines and 14 clock drivers, including LVPECL, LVDS and CMOS. This level of integration replaces several discrete components and, when compared with existing solutions, enables designers to reduce board space and bill-of-materials (BOM) costs for clocking by more than 50%.

In addition, integrating the VCO on-chip greatly diminishes risks associated with the failure of discrete oscillators, improving overall system reliability.

The AD9516’s combination of integration and performance is ideal for applications such as wireless and wired infrastructure, optical networks, WiMAX basestations, medical imaging, automated test equipment and other instrumentation, that require low phase noise and low jitter in the clock path.

‘Global demand for communication services continues to rise, and manufacturers must constantly reduce the size and cost of equipment while maintaining high standards of service and quality’, said Kevin Kattmann, Product Line Director, High-Speed Signal Processing, Analog Devices.

‘For designers working on wireless basestations, optical networks, and telecom applications, the on-chip VCO eliminates a large discrete oscillator, while the 14 output channels will often provide all of the clocks needed on the transceiver or line card, simplifying space considerations and lowering system costs’.

The AD9516 has five versions, each supporting a specific frequency range.

On the high end, the AD9516-0 includes a VCO that tunes from 2.60 to 2.95GHz.

The other parts cover lower frequencies, down to the AD9516-4’s VCO range of 1.50 to 1.90GHz.

Any of the AD9516 family may also be used with an external VCO up to 2.4GHz.

Each device features six LVPECL outputs, which operate up to the maximum VCO rate, as well as four/eight outputs which may be programmed to either LVDS (four outputs maximum) or CMOS (eight outputs maximum) levels.

In LVDS mode the outputs operate to 1GHz, and in CMOS mode the outputs operate to 250MHz.

The AD9516-0/1/2/3/4 devices are packaged in 9 x 9mm, 64-lead LFCSP (lead-frame chip-scale packages) and priced at US $10.75 per unit in 10,000-piece quantities.

C-Mac MicroTechnology reckons it has taken the hard work out of finding the best frequency control component for a particular application with its new online part locator.

C-Mac MicroTechnology reckons it has taken the hard work out of finding the best frequency control component for a particular application with its new online part locator. Using this new tool, engineers simply type their key requirements into an intuitive online form to output a reference table of suitable oscillators, with quick links to the full specification sheet for each. The part locator covers C-Mac’s entire range of standard crystal oscillator products, including OCXOs (oven controlled crystal oscillators), TCXOs (temperature compensated crystal oscillators), VCXOs (voltage controlled crystal oscillators), SPXOs (simple packaged crystal oscillators), factory programmable oscillators for fast delivery, and oscillators approved by communications chipset manufacturers Semtech and Zarlink Semiconductor.

Users first enter four required parameters - output frequency, operating temperature range, frequency stability over temperature range, and supply voltage - and then have the option of also specifying voltage control of output frequency, manual frequency adjustment capability, output waveform, package style and RoHS compatibility.

Other characteristics of each resulting oscillator range can be assessed by viewing the downloadable data sheets.

‘C-Mac’s current frequency product databook is over 300 pages thick, so picking out the best specification for the application at hand is not a trivial undertaking’, said Stuart Clifton, General Manager of C-Mac’s Frequency Control Products business unit.

‘Engineers are busy people, so we thought we’d make life a little easier for them’.

Due to the wide range of parameters that can be specified, it is inevitable that certain combinations will not yield results from C-Mac’s standard product range.

However, the company’s engineers are well versed in producing custom components to individual requirements, and simply hitting the ‘request info’ button will automatically send the specifications to C-Mac for evaluation.
