CY28401 - 100-MHz Differential Buffer

General Description

The CY28401 is a differential buffer and serves as a companion 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.

Key Features

  • CK409 or CK410 companion buffer.
  • Eight differential 0.7v clock pairs.
  • Individual OE controls.
  • Low CTC jitter (< 50 ps).
  • Programmable bandwidth.
  • SRC_STOP# power management control.
  • SMBus Block/Byte/Word Read and Write support.
  • 3.3V operation.
  • PLL Bypass-configurable.
  • Divide by 2 programmable.
  • 48-pin SSOP package Functional.
