ICS9DB803D

EIGHT OUTPUT DIFFERENTIAL BUFFER FOR PCIE GEN1 AND GEN2 DATASHEET ICS9DB803D General Description The ICS9DB803D is compatible with the Intel DB800v2 Differential Buffer Specification. This buffer provides 8 PCI-Express Gen2 clocks. The ICS9DB803D is driven by a differential output pair from a CK410B+, CK505 or CK509B main clock generator. Recommended Application DB800v2 compatible part with PCIe Gen1 and Gen2 Support 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 Features/Benefits Spread spectrum modulation tolerant, 0 to -0.5% down spread and +/- 0.25% center spread Supports undriven differential outputs in PD# and SRC_STOP# modes for power management Key Specifications Outputs cycle-cycle jitter < 50ps Output to Output skew <50ps Phase jitter: PCIe Gen1 < 86ps peak to peak Phase jitter: PCIe Gen2 < 3.0/3.1ps rms Functional Block Diagram OE _ (7 : 0 ) 8 SRC _IN SRC _IN # SPR EAD C OM PAT IBLE PLL M U X ST OP L O GI C 8 D IF(7:0)) SRC _ST OP# H IGH _BW # B YP A S S # / PL L PD# SDAT A SCLK C ON T R OL LOGIC I RE F LOC K Note: Polarities shown are for OE_INV=0.
