CY2DL1504 1:4 Differential LVDS Fanout Buffer with Selectable Clock Input na1:4 Differential LVDS Fanout Buffer with Selectable Clock Input Features Functional Description Select one of two differential (LVPECL, LVDS, HCSL, or CML) The CY2DL1504 is an ultra-low noise, low-skew, input pairs to distribute to four LVDS output pairs low-propagation delay 1:4 differential LVDS fanout buffer targeted to meet the requirements of high-speed clock Translates any single-ended input signal to 3.3 V LVDS levels distribution applications. The CY2DL1504 can select between with resistor bias on INx input two separate differential (LVPECL, LVDS, HCSL, or CML) input clock pairs using the IN SEL pin. The synchronous clock enable 30 ps maximum output-to-output skew function ensures glitch-free output transitions during enable and 480 ps maximum propagation delay disable periods. The output enable function allows the outputs to be asynchronously driven to a high-impedance state. The device 0.11 ps maximum additive RMS phase jitter at 156.25 MHz has a fully differential internal architecture that is optimized to (12 kHz to 20 MHz offset) achieve low-additive jitter and low-skew at operating frequencies Up to 1.5 GHz operation of up to 1.5 GHz.
