CY2DP1504 1:4 LVPECL Fanout Buffer with Selectable Clock Input 1:4 LVPECL Fanout Buffer with Selectable Clock Input Features Functional Description Select one of two differential (LVPECL, LVDS, HCSL, or CML) The CY2DP1504 is an ultra-low noise, low-skew, input pairs to distribute to four LVPECL output pairs low-propagation delay, 1:4 LVPECL fanout buffer targeted to meet the requirements of high-speed clock distribution Translates any single-ended input signal to 3.3 V LVPECL applications. The CY2DP1504 can select between separate levels with resistor bias on INx input differential (LVPECL, LVDS, HCSL, or CML) input clock pairs using the IN SEL pin. The synchronous clock enable function 30 ps maximum output-to-output skew ensures glitch-free output transitions during enable and disable 480 ps maximum propagation delay periods. The device has a fully differential internal architecture that is optimized to achieve low additive jitter and low skew at 0.15 ps maximum additive RMS phase jitter at 156.25 MHz operating frequencies of up to 1.5 GHz.
