Cable Driver
The M21202 is a next generation high performance analog
> KEY FEATURES
SD-SDI video co-axial cable driver solution that is pin-to-pin,
electrically, and functionally compatible with existing legacy
> SMPTE 259M and SMPTE 344M
compliant
single channel cable drivers.
> Supports data rate operation
Superior next generation cable driving and output return
of 143, 177, 270, 360, 540 Mbps
and DVB-ASI at 270 Mbps
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

• 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).
