M21145 [6.5 Gbps 80x80] and M21165 [6.5 Gbps 160x160] Crosspoint Switch

The M21145/M21165 are 80x80/160x160 asynchronous fully non-blocking crosspoint switches operating at data

rates up to 6.5 Gbps. The M21145/M21165 can be configured either to switch channels as individual lanes (Lane

Mode) or in groups of four (Group Mode). The devices include advanced signal conditioning capabilities that enable

the transmission of 6.5 Gbps NRZ data over PCB channels that exceed one meter in length. Signal conditioning

circuits counter frequency dependent impairments in the channel. Specific device capabilities include individual,

per-lane input equalization and output de-emphasis. Configuration of the device is done through a set of register

writes using one of the integrated 2-wire serial (I²C compatible) or 4-wire serial digital interfaces.

Product Overview

Power at 1.2V (W)

Programmable per lane input equalization up to 23 dB

Fully non-blocking array switch matrices

Programmable output de-emphasis to 6db

Protocol agnostic

Support for video pathological patterns

2-wire I²C, 4-wire SPI, and 8-bit data parallel interface registers Flexible and complete control for configuration

1.2V core power supply operation / 1.2 or 1.8 IO optional

Low power consumption at 11.5W (M21145) and 22.9W (M21165)

Individual level loss of signal (LOS) alarm and squelch

JTAG boundary scan

Extended temperature operation: 0°C to 85°C
