PI6LC48P04LIEX Overview

4-OUTPUT LVPECL NETWORKING CLOCK

PI6LC48P04
4-Output LVPECL Networking Clock Generator
Features
ÎÎ
Four differential LVPECL output pairs
ÎÎ
Selectable crystal oscillator interface or LVCMOS/LVTTL
Description
The PI6LC48P04 is a 4-output LVPECL synthesizer optimized
to generate Ethernet and Fibre Channel reference clock frequen-
cies and is a member of Pericom’s HiFlex family of high perfor-
mance clock solutions. Using a 26.5625MHz or a 26.04166MHz
crystal, the following frequencies can be generated based on
the settings of 2 frequency select pins (N_SEL[1:0]): 212.5MHz,
159.375MHz, 106.25MHz, 53.125MHz, and 156.25MHz.
The PI6LC48P04 uses Pericom’s proprietary low phase noise
VCO technology and can achieve less than 1ps typical rms
phase jitter, so it is ideal for Ethernet interface in all kind of
systems.
