General Description

PT4455 is a high performance OOK/ASK 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 control the phase-locked loop and power amplifier to have fast start-up time in operation.
