The BCM82181 is an 8-channel bidirectional repeater device footprint-compatible to the Broadcom BCM82381 bidirectional retimer device.

The new devices are designed to address low power requirements while providing sufficient link performance to meet the IEEE 802.3 25/100GbE and 32GFC requirements for backplane, front panel and active copper applications.

“With the addition of the BCM82109 and BCM82181 low power 28Gbps repeater devices, Broadcom now has a complete portfolio of signal conditioning solutions allowing our expanded customer base to solve a myriad of signal integrity challenges at 25/28Gbps signaling,” said Lorenzo Longo, senior vice president and general manager of the Physical Layer Products Division at Broadcom.

Features:

 Power consumption < 100 mW per channel

 Compensates up to 16 dB of channel loss while providing additional Tx pre-emphasis

 Supports link training, auto negotiation and FEC pass-through

 No reference clock needed

 Dual supply: 1.0V and 2.5V/3.3V

 Dual control interface: MDC/MDIO and BSC
