Introduction
Thank you for your interest in the CY3677 Evaluation Kit (EVK). The CY3677 EVK is designed to enable you to evaluate the
programmable clock device CY29430, the latest addition to the Cypress timing product portfolio. The clock device CY29430
is a high-performance programmable oscillator with one fractional PLL that generates any frequency up to 2.1 GHz with jitter
as low as 110 fs. The device offers one differential output and one single-ended output. The device can be configured to
generate either a single-ended output or a differential output but not both simultaneously. The device comes in a 16-pin QFN
package for industrial applications. The differential I/O standards supported are LVDS, LVPECL, High-Speed Current Steering
Logic (HCSL), and Current Mode Logic (CML). The single-ended signal supported is LVCMOS. The device also supports
features such as a Voltage-Controlled Crystal Oscillator (VCXO), and provides the user with an I
2
C programming interface.
The device supports four frequency profiles, which can be switched dynamically using external Frequency Select (FS0 and
FS1) signals. There are two jumpers provided on the EVK to perform frequency selection on the board.
The CY3677 EVK allows you to evaluate output clock signals by making required on-board termination settings.
The CY3677 EVK is available through the
Cypress Online Store
or through our distributors.
