PI6C4911505-04
High Performance 1:5 LVPECL Fanout Buffer
Features
ÎÎ5 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 PI6C4911505-04 is a high performance fanout buffer device-
which supports up to 1.5GHz frequency. The device has 2 select-
able clock inputs that can accept most differential and single
ended clock sources. This device is ideal for systems that need to
distribute low jitter clock signals to multiple destinations.
Applications
ÎÎNetworking systems including switches and Routers
ÎÎHigh frequency backplane based computing and telecom
platforms
