Integrated Device Technology Crystal-to-0.7V Differential HCSL/LVCMOS Frequency Synthesizer 841S012DKILFT

The 841S012DI is an optimized PCIe, sRIO and Gigabit Ethernet Frequency Synthesizer and a member of family 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 communication processors, DSPs, switches and bridges.
