描述 Description

Output Features

The ICS9DB403 is compatible with the Intel DB400v2 Differential

Buffer Specification. This buffer provides 4 PCI-Express Gen2 clocks.

The ICS9DB403 is driven by a differential output pair from a

CK410B+, CK505 or CK509B main clock generator.

• 4 - 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

Key Specifications

• Outputs cycle-cycle jitter < 50ps

• Outputs skew: 50ps

• Phase jitter: PCIe Gen1 < 86ps peak to peak

• Phase jitter: PCIe Gen2 < 3.0/3.1ps rms

• 28-pin SSOP/TSSOP pacakge

• Available in RoHS compliant packaging

• Supports Commercial (0 to +70°C) and Industrial (-40 to

+85°C) temperature ranges

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.
