Overview
TheCY23020-3 is a high-performance 400-MHz LVPECL
Output phase-locked loop (PLL)-based zero delay buffer
(ZDB) designed for high- speed clock distribution applications.
The device features a guaranteed TTB window specifying all
occurrences of output clocks with respect to the input
reference clock across variations in voltage, temperature,
process, frequency, and ramp rate.
Additionally, the CY23020-3 can be used as a fan-out buffer
via the S[1:2] control pins. In this mode, the PLL is bypassed
and the reference clock is routed to the output buffers.
