4x4 1.6 Gbps Crosspoint with Quad Channel Multi-rate Video Reclockers for SD/HD (42 Mbps to 1.6 Gbps) Applications M21260 The M21260 is part of a family of low-power, high-performance video devices for broadcast and professional video applications. In addition to the 4x4 crosspoint with independent quad channel video reclockers, other video products include: - M21250, M21251, M21252 quad channel reclockers for SD, SD/HD, and SD/HD/2xHD data rates - M21261 1:4 1.6 Gbps video fanout with SD/HD multi-rate reclocking - M21262 4:1 1.6 Gbps video selector with SD/HD multi-rate reclocker The M21260 provides all of the features and benefits of the M21251 quad channel SD/HD reclocker and incorporates a fully non-blocking 4x4 asynchronous crosspoint switch before the reclocker stages. Reduced power dissipation with improved jitter generation, tolerance, and transfer enable robust system design at reduced cost and simplified thermal management.

The device can be controlled through nations, and PCB layout friendly features facilitate quick PCB turn hardwired pins or a SPI compatible 4 wire serial interface. times while helping to maintain signal integrity. The hardwired mode simplifies the overall design, while allowing control of key features while the SPI interface with an external microcontroller enables complete control of the device functions.
