PI6C20400S

1:4 Clock Driver for Intel

PCI Express Chipsets

Features

Description

• Phase jitter ﬁlter for PCIe Gen II application

• Four Pairs of Differential Clocks

• Low skew < 50ps

Pericom Semiconductor's PI6C20400S is a PCI Express GenII

compliant high-speed, low-noise differential clock buffer designed

to be companion to PI6C410BS. The device distributes the

differential SRC clock from PI6C410BS to four differential pairs

of clock outputs either with or without PLL. The clock outputs

are controlled by input selection of SRC_STOP#, PWRDWN#

and SMBus, SCLK and SDA. When input of either SRC_STOP#

or PWRDWN# is low, the output clocks are Tristated. When

PWRDWN# is low, the SDA and SCLK inputs must be Tri-

stated.

• Low jitter < 50ps cycle-to-cycle

• < 1 ps additive RMS phase jitter

• Output Enable for all outputs

• Outputs tristate control via SMBus

• Programmable PLL Bandwidth

• 100 MHz PLL Mode operation

• 100 - 400 MHz Bypass Mode operation

• 3.3V Operation

• Packaging (Pb-free and Green):

— 28-Pin SSOP (H28) & 28-Pin TSSOP (L28)
