Description
The PI6LC48P25104 is a single output LVPECL synthesizer
optimized to generate Ethernet reference clock frequencies and
is a member of Pericom’s HiFlex family of high performance
clock solutions. Using a 25MHz, it can generate 156.25MHz, or
187.5MHz output. Using other crystal frequencies, it can gener-
ate other popular frequencies for networking and server storage
systems.
The PI6LC48P25104 uses Pericom’s proprietary low phase noise
PLL technology to achieve ultra low phase jitter, so it is ideal for
SATA/SAS or Ethernet interface in all kind of systems.
