Description:

The ICS9DB803D is a differential buffer designed to be compatible with the Intel DB800v2 Differential Buffer Specification. It provides 8 PCI-Express Gen2 clocks and is driven by a differential output pair from a CK410B+, CK505, or CK509B main clock generator.

Features:

- 8 output differential pairs with 0.7V current-mode logic

- Supports zero delay buffer mode and fanout mode

- Bandwidth programming is available

- Operates at 50-100 MHz in PLL mode and 50-400 MHz in Bypass mode

- Tolerant to spread spectrum modulation, with 0 to -0.5% downspread and +/- 0.25% center spread

- Supports undriven differential outputs in PD# and SR C_STOP# modes for power management

- Key specifications include cycle-cycle jitter < 50ps, output to output skew <50ps, and phase jitter of < 86ps peak to peak for PCIe Gen1 and < 3.0/3.1ps rms for PCIe Gen2

Applications:

The ICS9DB803D is recommended for use as a DB800v2 compatible part with PCIe Gen1 and Gen2. It is suitable for applications requiring high-speed differential buffering for PCI-Express interfaces.
