3G/HD/SD-SDI Ultra Low Power Reclocker
The M31245 is a low power, multi-rate, highly integrated digital video reclocker with
dual outputs for SMPTE compliant SDI data rates and DVB-ASI video and digital
audio applications. The reclocker input provides high jitter tolerance and input
equalization for up to 60" of FR4 trace. A built-in automatic rate detection circuit
locks to 270 Mbps, 1.4835/1.485 Gbps, and 2.967/2.97 Gbps data rates. The device
operates without the need for a reference clock and also supports the MADI audio
standard. The device operates using a single 2.5 V supply voltage and has extremely
low power consumption with the reclocker dissipating only 70 mW. The reclocker
could be used in either hardware mode or controlled through a standard four-wire
serial digital interface. The M31245 also features advanced diagnostic capabilities
such as total jitter measurement on input, data rate detection, Loss of Signal (LOS),
and Loss of Lock (LOL) detection. The M31245 is offered in a compact green and
RoHS compliant 4 mm x 4 mm, 32-pin QFN package.
