SP1455B PCM SIGNAL MONITOR

SP1450B(B) SP1450B{B) & SP1455B{B) PCM SIGNAL MONITOR CIRCUITS The SP1450 and SP1455 are bipolar integrated circuits designed to monitor errors in three-level digital signals modulated by a three-alphabet 4B3T code such as MS43. They can also indicate the failure of positive or negative pulses in the signal. The high frequency capability allows operation in PCM systems up to 34M bitls (SP1450) and 140M bitls (SP1455). Facilities are provided to adjust input thresholds independently on each pol.

SP1455B Features
