12G Multi-rate Reclocker

The M23145 is a multi-rate, highly integrated digital video reclocker with dual outputs for the next generation SMPTE compliant SDI and DVB-ASI video as well as digital audio applications. The reclocker input provides high input jitter tolerance and input jitter equalization. A built-in automatic rate detection circuit locks the reclocker to 270 Mbps, 1.4835/1.485 Gbps, 2.967/2.97 Gbps, 5.934/5.94 and 11.868/11.88 Gbps. The device operates without the need of a reference clock and also supports the MADI audio standard. The M23145 operates using a single 2.5 V supply voltage and has low power consumption. The reclocker can be used in either hardware mode or controlled through a standard four-wire digital interface in software mode. The M23145 features advanced diagnostic capabilities such as loss of signal (LOS) detection, input jitter diagnostics, data rate detection and Loss of Lock (LOL). The device also offers power management functions such as power down upon loss of signal.
