Functional Description
The CY2DL1504 is an ultra-low noise, low-skew, low-propagation delay 1:4 differential LVDS fanout buffer targeted to meet the requirements of high-speed clock distribution applications. The CY2DL1504 can select between two separate differential (LVPECL, LVDS, HCSL, or CML) input clock pairs using the IN_SEL pin. The synchronous clock enable function ensures glitch-free output transitions during enable and disable periods. The output enable function allows the outputs to be asynchronously driven to a high-impedance state. 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.
