GENERAL DESCRIPTION

The 841S012DI is an optimized PCIe, sRIO and Gigabit Ethernet

Frequency Synthesizer and a member of high performance clock

solutions from IDT. The 841S012DI uses a 25MHz parallel resonant

crystal to generate 33.33MHz - 200MHz clock signals, replacing

multiple oscillators and fanout buffer solutions. The device supports

±0.25% center-spread, and -0.5% down-spread clocking with two

spread select pins (SSC[1:0]). The VCO operates at a frequency of

2GHz. The device has three output banks: Bank A with two 100MHz

– 250MHz HCSL outputs; Bank B with seven 33.33MHz – 200MHz

LVCMOS/ LVTTL outputs; and Bank C with one 33.33MHz – 200MHz

LVCMOS/LVTTL output.

All Banks A, B and C have their own dedicated frequency

select pins and can be independently set for the frequencies

mentioned above. The low jitter characteristic of the 841S012DI

makes it an ideal clock source for PCIe, sRIO and Gigabit Ethernet

applications. Designed for networking and industrial applications,

the 841S012DI can also drive the high-speed clock inputs of com-

munication processors, DSPs, switches and bridges.
