M21214 HD/SD Broadcast Video
Adaptive Co-Axial Cable Equalizer
The M21214 is a next generation high performance analog
SD/HD video cable adaptive equalizer that provides > 175m
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
M21214 is complemented with a complete serial routing
chipset that includes reclocking (M21215) and cable drivers
(M21212/M21218) devices. These new devices further
complement Mindspeed’s unique HD/SD quad channel
reclocking and asynchronous switching devices:
• M21250, M21251, M21252 quad channel multi-rate
video reclockers
• 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
A unique, patent pending equalization approach improves
SD-SDI and HD-SDI performance such that typical HD
applications can be connected with a single link facilitating a
lower overall facility system cost.
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 GS1524 multi-rate SDI
adaptive cable equalizer.
Mindspeed’s innovative circuit architecture enables next
generation systems with flexible power supply operation of
2.5V to 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 decks.
