Programmable clocks provide versatility

InstaClock enables customers to reduce inventory and device qualification requirements by ordering a single part number to support multiple designs.

Cypress Semiconductor has added released the CY22801 programmable clock generator.

Users can generate any desired frequency for the clock with CyClocksRT software.

The new InstaClock chip supports frequencies used in virtually any consumer electronic and communications applications, including Ethernet, PCI, USB, CPU, HDTV and audio.

In addition, Cypress has added more than 60 widely used clock configurations to those available for the original InstaClock chip, the CY22800, which can be programmed instantly with any configuration within the list of defined frequencies.

The CY22800 also features programmable spread spectrum from +/-0.25% to +/-2.0% a Lexmark Profile for maximum EMI reduction, and VCXO capabilities with a pull-range of +/-150 parts per million to provide flexible crystal selection.

Both InstaClock devices have a single integrated phase-locked loop and deliver low-jitter and high-accuracy outputs.

"The fully configurable CY22801 programmable clock generator brings the ability to easily to generate your own samples in a matter of minutes to a wide range of applications, significantly expanding the reach of the InstaClock family", said Wayne Gill, Managing Director for Cypress' General Purpose Clocks business unit.

"On top of delivering low-jitter and high-accuracy outputs, InstaClock enables customers to reduce inventory and device qualification requirements by ordering a single part number to support multiple designs".

Designers can use the CY36800 InstaClock Programmable Clock Generator kit to program InstaClock samples.

The kit contains three samples each of the CY22800 and CY22801 general purpose InstaClock devices, a programmer board with a USB connector and a USB cable.

The kit allows for instant programming of CY22800 and CY22801 InstaClock samples, meaning the same device can be used to address many common applications for programmable clocks in end-user systems and many crystal or oscillator-generated frequencies in those systems.

By allowing for self-serve programming, the kit enables engineers to streamline the process of tuning clocks and to reduce the development cycle as clock requirements and board designs change during prototype development.

Once the desired clock configuration is determined with the kit, Cypress distribution partners have the programming capability to support the production requirements.

The CY22800 and CY22801 general purpose InstaClock devices are available in an eight-pin SOIC package and are currently in production.
