Technical content
The M21204 is a next generation high performance analog SD-SDI video cable adaptive equalizer that provides > 350m Belden 1694A cable length performance in a drop in solution that is pin-to-pin, electrically, and functionally compatible with existing legacy single channel cable equalizers. Superior next generation equalization performance of the M21204 is complemented with a complete serial routing chipset that includes reclocking (M21205) and cable drivers (M21202) devices. These new devices further complement Mindspeed’s unique SD-SDI and HD/SD quad channel reclocking and asynchronous switching devices:
- M21252 quad channel multi-rate SD-SDI video reclocker
- M21260 4x4 1.6 Gbps video crosspoint switch with quad multi-rate reclockers
- M21261 1:4 1.6 Gbps video fanout with HD/SD multi-rate reclocking
- M21262 4:1 1.6 Gbps video selector with HD/SD multi-rate reclocker DC restoration to compensate for pathological signal DC content, cable length indication for data rates to 360 Mbps, and a voltage programmable mute threshold are included for full compatibility with the GS9064 multi-rate SD-SDI cable equalizer. Mindspeed’s innovative circuit architecture enables next generation systems with flexible power supply operation of 2.5V or 3.3V with a 35% power reduction at 2.5V supply rails and a wider operating temperature range (-10°C to +85°C) for outdoor applications such as camcorders and edit deck s.
