Resources for 844S012I-01
Description
The 844S012I-01 is an optimized PCIe, sRIO and Gigabit Ethernet Frequency Synthesizer. The 844S012I-01 uses a 25MHz parallel resonant crystal to generate 33.33MHz - 200MHz clock signals, replacing solutions requiring multiple oscillator and fanout buffer solution. The device supports ±0.25% center-spread, and -0.6% down-spread clocking with two spread select pins (SSC[1:0]). The VCO operates at frequency of 2GHz. The device has three output banks: Bank A with two LVDS outputs, 100MHz – 250MHz; 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 844S012I-01 makes it an ideal clock source for PCIe, sRIO and Gigabit Ethernet applications. Designed for networking and industrial applications, the 844S012I-01 can also drive the high-speed clock inputs of communication processors, DSPs, switches and bridges. The 843241I-04 is a Serial ATA (SATA)/Serial Attached SCSI (SAS) Clock Generator and a member of the HiPerClocksTM family of high performance devices from IDT. For SATA/SAS applications, a 25MHz crystal is used to produce 150MHz. The 843241I-04 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
