Description
The PI6LC48P0405 is a 4-output LVPECL synthesizer optimized
to generate 125MHz clock frequencies and is a member of Peri-
com’s HiFlex family of high performance clock solutions.
The PI6LC48P0405 uses Pericom’s proprietary low phase noise
VCO technology and can achieve less than 0.32ps typical rms
phase jitter, it is ideal for Ethernet interface in all kind of sys-
tems.
