Description
The PI6LC48L0201A is a 2-output LVDS 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 crystal, the most popular Ethernet
frequencies can be generated based on the settings of 2 frequen-
cy select pins.
The PI6LC48L0201A 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.
