PI6LC48P04
4-Output LVPECL Networking Clock Generator
Features
ÎÎFour differential LVPECL output pairs
ÎÎSelectable crystal oscillator interface or LVCMOS/LVTTL
single-ended clock input
ÎÎSupports the following output frequencies: 212.5MHz,
159.375MHz, 106.25MHz, 53.125MHz, 156.25MHz,
187.5MHz
ÎÎRMS phase jitter @ 212.5MHz, using a 26.5625MHz crystal
(12kHz – 20MHz): 0.3ps (typical)
ÎÎFull 3.3V or 2.5V supply modes
ÎÎ-40°C to 85°C ambient operating temperature
ÎÎAvailable in lead-free package: 24-TSSOP
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.

Note: Electrical parameters are quaranteed over the specified ambient operating temperature range, which is established when the device is mounted in a test
socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal equilibrium has been reached under these
conditions.
Note1: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the differential cross points.
Note2: This parameter is defined in accordance with JEDEC Standard 65.
Note3: Please refer to the Phase Noise Plots.
