Transmitter IC


PT4452

PT4452 is a high performance OOK/ASK/FSK transmitter for the Remote Keyless Entry (RKE) systems. It consists of a power amplifier, one-shot circuit and phase-locked loop with internal voltage controlled oscillator and loop filter. The one-shot circuit controls the phase-locked loop and power amplifier to have fast start-up time in operation.
