CY28401 Datasheet 100-mhz Differential Buffer

Manufacturer: Cypress (now Infineon)

Overview: CY28401 100-MHz Differential Buffer for PCI Express and SATA.

General Description

The CY28401 is a differential buffer and serves as a panion device to the CK409 or CK410 clock generator.

The device is capable of distributing the Serial Reference Clock (SRC) in PCI Express and SATA implementations.
