Product Description

CYF219 high performance OOK/ASK transmitter IC

DESCRIPTION:

CYF219 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.

FEATURES:                           

• Highly integrated OOK/ASK transmitter
