M21204 SD-SDI Broadcast Video
Adaptive Co-Axial Cable Equalizer
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

for SD and HD data rates
temperature range:
-10°C to +85°C
- 350m typical @ SD-SDI with
Belden 1694A
> Pin-to-pin, electrically,
and functionally compatible
with M21214, GS9064
> Output mute at maximum
equalized cable length with
manual override
• 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 decks.
