M31564中文资料3G/HD/SD-SDI Long Reach Equalizer with Jitter Cleaner数据手册MACOM规格书

描述 Description

The M31564 is a multi-rate, highly integrated, adaptive cable equalizer for SDI and DVB-ASI video as well as digital audio applications. It provides adaptive, low noise, high gain equalization for 75 Ohm coaxial cable at SDI 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 M31564 features an integrated jitter cleaner, which automatically removes the jitter generated at HD-SDI and 3G-SDI at the output of the equalizer, eliminating the need for standalone reclockers at the input and 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 M31564 offers a single output solution with a smaller footprint and maximum 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. 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 M31564 is offered in a green and RoHS compliant small footprint QFN package.
