Description
The PI6LC48P21 is a single output LVPECL synthesizer opti-
mized to generate Ethernet reference clock frequencies and is a
member of Pericom’s HiFlex family of high performance clock
solutions. Using a 25MHz or 26.6MHz crystal, it can generate
125MHz or 133MHz output frequencies.
The PI6LC48P21 uses Pericom’s 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
ÎÎNetworking systems
