M21235
HD/SD Broadcast Video Multi-rate Automatic
Reclocker
The M21235 is an evolution of Mindspeed’s single channel
HD/SD multi-rate reclocking technology that provides
significant power savings, superior performance, and
flexible power supply options when compared to other
competing single channel reclockers.
In addition to a smaller 7x7mm MLF package to enable
denser designs with simpified PCB layouts, the M21235 also
provides a new I²C serial interface for simplified control of
all functions and PCB layout.
The M21235 is complemented with the M21232 HD/SD
video cable driver in a 3x3mm MLF package, and the M21234
HD/SD video cable equalizer in a 5x5mm MLF package to
optimize performance and density in new multi-rate designs.
Additional unique Mindspeed devices include the HD/SD
quad channel reclocking and asynchronous switching families:
• M21250, DS-M21251, DS-M21252 quad channel multi-rate
video reclockers
• M21260 4x4 1.6 Gbps video crosspoint switch with
quad multi-rate reclockers
• DS-M21261 1:4 1.6 Gbps video fanout with HD/SD

output
> 2.5V or 3.3V operation
> Reduced power dissipation
- 325mW typical @ 2.5V
- 430mW typical @ 3.3V
> Increased operating
temperature range:
-10ºC to +85ºC
Mindspeed’s innovative circuit architecture enables next
generation systems with flexible power supply operation
of 2.5V to 3.3V with a > 50% typical power reduction at 2.5V
(40% at 3.3V) supply rails and a wider operating temperature
range (-10ºC to +85ºC) and now with simplified control.
The additional functionality previously available on the
M21215 RSVD pins is now available thru the I²C interface
while basic functions such as Input selection, rate selection
or indication, and output mode control are still available
through hard-wired control pins.
