9SQ445 - Clock Generator

Description

The 9SQ445 is a single-chip, PCIe Gen6 clock synthesizer providing a subset of the 9SQ440 outputs.

It is designed to work as a complete clock solution or in combination with DB2000Q-compliant clock buffers to provide point-to-point clocks to multiple receiving agents.

Features

3.3V operation.
Side-Band Interface allows real-time hardware control of all output enables.
OE# pin control of 100M outputs.
85Ω differential Low-Power HCSL (LP-HCSL) outputs eliminate 24 resistors, saving 39mm2 of area.
Differential outputs drive both source terminated and double (receiver) terminated loads.
3 selectable SMBus addresses.
Supports 0%, -0.3% and -0.5% spread-spectrum amounts.
Packaged in 5 × 5 mm 40-VFQFPN Output Features.
Three 25MH.
