12.5 Gbps 80x80 Crosspoint Switches
The M21605, M21601 and M21080 are 160x160, 120x120 and 80x80, high-performance, asynchronous fully nonblocking crosspoint switches. They are ideally suited for high-speed data switching in datacom, telecom, Ultra High Definition Video (UHDTV) and 4K 60p definition applications. Each switching path can operate independently at any data rate of up to 12.5 Gbps, allowing for multi-rate routing and switching in one single device. Each input is equipped with a programmable equalizer capable of compensating up to 27 dB of loss at 12.5 Gbps. The output drivers are programmable, with up to 12 dB of post-tap and 5 dB of pre-tap deemphasis. Each lane is individually programmable and can be powered down if not used. The device can be operated from a single 1.8 V supply. The device is configurable through internal registers accessible by a 2-wire serial, 4-wire serial interface or an 8-bit parallel interface.
