CY2DP1504
Overview
- Functional Description The CY2DP1504 is an ultra-low noise, low-skew, low-propagation delay 1:4 LVPECL fanout buffer targeted to meet the requirements of high-speed clock distribution applications. The CY2DP1504 can select between two separate LVPECL input clock pairs using the IN_SEL pin. The synchronous clock enable function ensures glitch-free output transitions during enable and disable periods. The device has a fully differential internal architecture that is optimized to achieve low additive jitter and low skew at operating frequencies of up to 1.5 GHz.
