MODULATOR/PHASE LOCKED LOOP CIRCUITS FOR MODEMS
The SL650/1 are versatile integrated circuits capable of performing all the mon 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 variable frequency oscillator is programmable over a wide range of frequency by voltage, current, resistor or capacitor. In addition direct selection of one of four spot frequencies is facilitated...
