PI6C4911504-03

PI6C4911504-03 High Performance LVPECL Fanout Buffer Features ÎÎ4 LVPECL outputs ÎÎUp to 1.5GHz output frequency ÎÎUltra low additive phase jitter: < 0.03 ps (typ) (differential 156.25MHz, 12KHz to 20MHz integration range) ÎÎTwo selectable inputs ÎÎLow delay from input to output (Tpd typ. 1.5ns) ÎÎ2.5V / 3.3V power supply ÎÎIndustrial temperature support ÎÎTSSOP-20 package Description The PI6C4911504-03 is a high performance fanout buffer device which supports up to 1.5GHz frequency. PI6C4911504-03 features selectable single-ended clock or crystal inputs and translates to four LVPECL outputs. The outputs are synchronized with input clock during asynchronous assertion /deassertion of CLK_EN pin. PI6C4911504-03 is ideal for crystal or LVCMOS/ LVTTL to LVPECL translation. Typical clock translation and distribution applications are data-communications and telecommunications.This device is ideal for systems that need to distribute low jitter clock signals to multiple destinations.
