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.
