DS25BR400 - Quad Transceiver

General Description

The DS25BR400 is a quad 250 Mbps

2.5 Gbps CML transceiver, or 8-channel buffer, for use in XAUI Fibre Channel backplane and cable applications.

With operation down to 250 Mbps, the DS25BR400 can be used in applications requiring both low and high frequency data rates.

DS25BR400 Quad Transceiver with Input Equalization and Output De-Emphasis May 2006 DS25BR400 Quad Transceiver with Input Equalization and Output De-Emphasis General Description The DS25BR400 is a quad 250 Mbps – 2.5 Gbps CML transceiver, or 8-channel buffer, for use in XAUI Fibre Channel backplane and cable applications. With operation down to 250 Mbps, the DS25BR400 can be used in applications requiring both low and high frequency data rates. Each input stage has a fixed equalizer to reduce ISI distortion from board traces. The equalizers are grouped in fours and are enabled through two control pins. These control pins provide customers flexibility in XAUI applications where ISI distortion may vary from one direction to another.
