Timing solutions provider Cypress Semiconductor Corp. has introduced a clock chip and self-service programming kit that together enable programming of commonly used frequencies. Designers can use the new InstaClock programmable clock generator kit to program InstaClock samples with any configuration in a set of defined frequencies in less than a minute, eliminating the lead time of waiting for custom-programmed parts or for a mask change. Another benefit is that the kit reduces the number of components necessary for multiple frequencies by providing the same footprint for a wide range of configurations and applications. The reprogrammable InstaClock chips feature EMI reduction and VCXO capabilities and support frequencies used in Ethernet, PCI, USB, HDTV, and audio applications.

The CY36800 programming kit provides access to the most commonly used clock frequencies with a simple software selection and supplies a standard part number that can be ordered from authorized distributors. Additional configurations and frequencies are available as online downloads. The kit allows for instant programming of CY22800 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.

The CY36800 InstaClock programmable clock generator kit contains:
• five samples of the CY22800 general purpose InstaClock.
• a programmer board with USB connector and a USB cable.
• a CD-ROM containing software and ordering information.

Cypress's CY22800 general purpose InstaClock features:
• general-purpose clock synthesizer - microprocessor, USB, Ethernet, PCI, HDTV, digital audio, and other standard frequencies.
• EMI reduction - programmable spread spectrum from ±0.25% to ±2.0% and Lexmark Profile for maximum EMI reduction.
• VCXO - pull-range of ±150 ppm provides flexible crystal selection.

The CY36800 InstaClock kit is available free of charge from authorized Cypress distributors or for $19.95 from the Cypress online store. The CY22800 general-purpose InstaClock is available in an 8-pin SOIC package and is currently in production.
