M31544, M31564 3G/HD/SD-SDI Long Reach Adaptive Cable Equalizer with Integrated Jitter Cleaner The M31544/64 are multi-rate, highly integrated, adaptive cable equalizers for SDI and DVB-ASI video as well as digital audio applications. It provides adaptive, low noise, high gain equalization for 75 coaxial cables at SDI and MADI data rates from 125 Mbps to 2.97 Gbps. The device is capable of compensating for losses accumulated across cable length up to 200 m when operating at 2.97 Gbps. The M31544/64 feature an integrated jitter cleaner, which automatically removes the jitter generated at HD-SDI and 3G-SDI data rates at the output of the equalizer, eliminating the need for standalone reclockers at the input, reducing system cost, complexity and power consumption. The jitter cleaner may be powered down and bypassed in applications where it is not required to allow for optimized power consumption for each application. The M31544 also features dual differential outputs, eliminating the need for additional circuitry and simplifying system design. Both outputs feature programmable swing as well as de-emphasis for enabling the signal to be transmitted across 40 of FR4 trace. The second, optional output may be disabled for additional power savings. The device operates using a single 2.5 V supply voltage and has extremely low power consumption with the equalizer and jitter cleaner dissipating only 145 mW when one output driver is enabled. It may be used in either hardware mode, or controlled through a standard four-wire serial digital interface. Furthermore, it features advanced diagnostic capabilities such as cable length indication, loss of signal detection, and offers power management functions such as power down upon loss of signal. The M31544/64 are offered in a green and RoHS compliant small footprint QFN package.
