Description
The PI6LC48P03A is a 3-output LVPECL synthesizer opti-
mized 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 set-
tings of 4 frequency select pins.
The PI6LC48P03A 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
