This high-frequency waveform generator can produce accurate triangle, sawtooth, sine, square, and pulse waveforms with minimal external components required. It offers a wide frequency range, adjustable from 0.1Hz to 20MHz, using an internal 2.5V bandgap voltage reference along with an external resistor and capacitor. Additionally, it allows for versatile control of the duty cycle through a ±2.3V control signal. This enables pulse-width modulation and sawtooth waveform generation. It also supports frequency modulation and sweeping, with independent controls for duty cycle and frequency. Thus making it a versatile tool for various waveform generation tasks.

Sine, square, or triangle waveforms can be selected at the output by setting the appropriate code at two TTL-compatible select pins. The output signal for all waveforms is a 2VP-P signal that is symmetrical around the ground. The low-impedance output can drive up to ±20mA.

The TTL-compatible SYNC output from the internal oscillator maintains a 50% duty cycle—regardless of the duty cycle of the other waveforms—to synchronize other devices in the system. The internal oscillator can be synchronized to an external TTL clock connected to PDI.
