Description
The PI6LC48P03 is a 3-output LVPECL synthesizer optimized to
generate Ethernet reference clock frequencies and is a member
of Pericomâs HiFlex family of high performance clock solutions.
Using a 31.25MHz or 26.041666MHz crystal, the most popular
Ethernet frequencies can be generated based on the settings of 4
frequency select pins.
The PI6LC48P03 uses Pericomâs proprietary low phase noise
PLL technology to achieve ultra low phase jitter, so it is ideal for
Ethernet interface in all kind of systems.
Applications
ÃÃNetworking systems
