DATASHEET EIGHT OUTPUT DIFFERENTIAL BUFFER FOR PCIE GEN1 AND GEN2 ICS9DB803D General Description Features/Benefits The ICS9DB803D is compatible with the Intel DB800v2 Spread spectrum modulation tolerant, 0 to -0.5% down Differential Buffer Specification. This buffer provides 8 spread and +/- 0.25% center spread PCI-Express Gen2 clocks. The ICS9DB803D is driven by a Supports undriven differential outputs in PD and differential output pair from a CK410B+, CK505 or CK509B SRC STOP modes for power management main clock generator. Key Specifications Recommended Application Outputs cycle-cycle jitter < 50ps DB800v2 compatible part with PCIe Gen1 and Gen2 Output to Output skew <50ps Support Phase jitter: PCIe Gen1 < 86ps peak to peak Phase jitter: PCIe Gen2 < 3.0/3.1ps rms Output Features 8 - 0.7V current-mode differential output pairs Supports zero delay buffer mode and fanout mode Bandwidth programming available 50-100 MHz operation in PLL mode 50-400 MHz operation in Bypass mode Functional Block Diagram 8 OE (7:0) SPREAD SRC IN COMPATIBLE PLL SRC IN M 8 STOP U DIF(7:0)) LOGIC X SRC STOP HIGH BW CONTROL BYPASS /PLL IREF LOGIC PD SDATA LOC K SCLK Note: Polarities shown are for OE INV=0.
