9DB1200C

DATASHEET Twelve Output Differential Buffer for PCIe Gen1/Gen2, QPI, and FBDIMM 9DB1200C Description DB1200 Rev 2.0 Intel Yellow Cover Device General Description The ICS9DB1200 is an Intel DB1200 Differential Buffer Specification device. This buffer provides 12 differential clocks at frequencies ranging from 100MHz to 400 MHz. The ICS9DB1200 is driven by a differential output from a CK410B+ or CK509B main clock generator. Output Features 12 - 0.7V current-mode differential output pairs. Supports zero delay buffer mode and fanout mode. Bandwidth programming available. 100-400 MHz operation in PLL mode 33-400 MHz operation in Bypass mode Features/Benefits 3 selectable SMBus addresses for easy system expansion Spread spectrum modulation tolerant, 0 to -0.5% down spread and +/- 0.25% center spread Supports undriven differential outputs in Power Down Mode for power management. Key Specifications Output cycle-cycle jitter < 50ps. Output to output s...
