Plessey SL651C
The SL650/1 are versatile integrated circuits capable of performing all the common modulation functions (AM, PAM, SCAM, FM, FSK, PSK, PWM, tone-burst, delta-modulation, etc,). The differential input phase comparator has a wide common mode input voltage range. It has a high gain limiting amplifier at its input requiring only lmV input to maintain lock range in a typical phase-locked loop.| Part No. | SL651C |
