Technical content
The M21202 is a next generation high performance analog SD-SDI video co-axial cable driver solution that is pin-t o-pin, electrically, and functionally compatible with existing legacy single channel cable drivers. Superior next generation cable driving and output return loss (>20dB) performance of the M21202 is complemented with a complete serial routing chipset that includes equaliza- tion (M21204) and reclocking (M21205) devices. These new devices further complement Mindspeed’s unique HD/SD and SD-SDI quad channel reclocking and asynchronous switching devices:
- M21252 quad channel multi-rate 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 In addition to being drop in compatible with the GS9068/9068A SD-SDI cable driver, the M21202 provides enhanced performance such as improved differential input sensitivity (100mVpp to 2000mVpp) and a typical device output return loss (ORL) of 20dB for easier board develop- ment and increased margin or headroom to the SMPTE specs. The M21202 is also pin-to-pin compatible with Mindspeed’s M21212/21218 cable driver but has a reduced maximum output swing of 1200 mVp-p single ended vs. 1800 mVp-p for the M21218. Mindspeed’s innovative circuit architecture enables next generation systems with flexible power supply operation of 2.5V or 3.3V and a wider operating tempature range (-10º to + 85ºC). Power dissipation is significantly reduced @ 3.3V (25%-42% typ/max) with further reductions possible @ 2.5V supply (40%-50% typ/max).
