PI6C21900

PCI Express Gen II1:19 Geared Differential Buffer

-17 and 2 Outputs

Description

Features

PI6C21900isaPCIExpressGenIIcompliant,high-speed,low-noise

PCI-Express and FBDIMM differential clock buffer designed to be

a companion to the workstation/server clock synthesizer such as

PI6C410B. Thedevicedistributesnineteencopiesofthedifferential

SRC clock, such as the one sourced from PI6C410B. To adapt to

different systems and to offer various performance platforms, the

PI6C21900outputscanbeprogrammedtodifferentfrequency. The

output frequency ratio can be modiﬁed to offer various derivative

frequency from the input frequency. Most of the output pair is

controlled by individual OE pin. Some OE# pins service multiple

differentialoutputpairs.Theclockoutputsarecontrolledbytheinput

• Phase jitter ﬁlter for PCIe Gen II application

• Nineteen Pairs of differential HCSL buffers

-17 and 2 outputs

• Low skew < 100 ps within Dif (17:0) group

• Low phase jitter < 108 ps (PLL mode)

• Output Enable (OE) pins for all outputs

• Outputs tristate control via SMBus

• Power Management Control

• Programmable PLL Bandwidth

• PLL or PLL Bypass (Fanout) mode

• Gear Ratios for different input to output frequencies

- Input: 100, 133, 166, 200, 266, 333, or 400 MHz

- Output: 100, 133, 166, or 200 MHz

• 3.3V Operation

SMBus, using SCL (SMBus Clock) and SDA (SMBus Data) pins.

• Packaging (Pb-Free and Green):

—72-pin TQFN (ZD)
