AC2301

10-Channel Differential Buffer

AC2301

Product Overview

The AC2301 is a 3GHz, 10-channel differential fanout buffer designed for high-frequency, low-jitter clock/data distribution and level translation. The input clock can be selected from two differential inputs or a single crystal input. The selected input clock is distributed to two output groups, each consisting of five differential outputs and one LVCMOS output with sync functionality.

Typical Applications:

Clock distribution and level translation for ADCs, DACs, XAUI, SATA/SAS, SONET/SDH, CPRI, Fibre Channel, Multi-Gigabit Ethernet, and high-frequency backplanes

Switches, routers, line interface cards, timing cards

Servers, computing, PCI Express (PCIe 3.0, 4.0)

Remote Radio Units and Base Station Units
