Functional Description

The CY2DP1510 is an ultra-low noise, low skew, low-propagation delay 1:10 LVPECL fanout buffer targeted to meet the requirements of high-speed clock distribution applications. The CY2DP1510 can select between two separate LVPECL input clock pairs using the IN_SEL pin. 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.
