SL652C
MODULATOR/PHASE LOCKED LOOP
The SL652C is a versatile integrated circuit 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 this device, 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 by using the on-chip binary interface, which accepts standard logic levels at very low logic '1' input currents.
