M21218 SD/HD Broadcast Video Co-axial
Cable Driver
The M21218 is a next generation high performance analog
SD/HD video co-axial cable driver solution that is pin-to-pin,
electrically, and functionally compatible with existing legacy
single channel cable drivers.

Superior next generation cable driving and output return
loss (ORL) performance of the M21218 is complemented with
a complete serial routing chipset that includes equalization
(M21214) and reclocking (M21215) devices. These new
devices further complement Mindspeed’s unique SD/HD
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 SD/HD
multi-rate reclocking
• M21262 4:1 1.6 Gbps video selector with SD/HD
multi-rate reclocker
In addition to being drop in compatible with Gennum’s
GS1528 multi-rate SDI dual slew-rate cable driver, the
M21218 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 development and increased margin or
headroom to the SMPTE specs.
Mindspeed’s innovative circuit architecture enables next
generation systems with flexible power supply operation of
1.8V to 3.3V with 48% to 60% typical to MAX power reduction
@ 1.8V (25% to 42% @ 3.3V) supply rails and a wider operating
temperature range (-10
°
to + 85
°
C).
