M21145/65 6.5 Gbps 80x80/160x160 Crosspoint Switch
> Product Overview
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.
Features
>> Programmable per lane input equalization up to 23 dB
Benefits
Allows control in removing deterministic jitter (ISI)
>> Fully non-blocking array switch matrices
Ultimate flexibility for switching and multicasting signals
>> Programmable output de-emphasis to 6db
Improves system jitter budget and drive reach
>> Protocol agnostic
One device supports multiple applications
>> Support for video pathological patterns
Robust solution for SDI applications
>> 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
Standard power supply supported
>> Low power consumption at 11.5W (M21145) and 22.9W (M21165) Low thermal and power management costs
>> Individual level loss of signal (LOS) alarm and squelch
Diagnostics for status
>> JTAG boundary scan
Improves manufacturing yield for configuration
>> Extended temperature operation: 0°C to 85°C
Provides higher tolerance and additional design margin
