SL651C MODULATOR/PHASE LOCKED LOOP

SL650/SL651 B/C SL650B & C SL651B & C MODULATOR/PHASE LOCKED LOOP CIRCUITS FOR MODEMS 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,). A wide variety of phase-locked loops can be realised using the SL650 or SL651, with all parameters accurately controllable; they can also be used to generate precise waveforms at frequencies up to 0.2MHz_ The highly accurate and stable .

SL651C Features

* low bias current (typically 25nA), fast recovery from overload, and a short-circuit output current of ±7.5mA. The auxiliary amplifier is omitted from the SL651. Fig. 1 Pin connections (top view) DG24 FEATURES

* VFO Frequency Variable Over 100: 1 Range With Same Capacitor: Linearity 0.2%
