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
• High output power, 3 .3V /+14 dBm / 20 mA(50% duty cycle)
• Low supply voltage, 1.8 V to 3.6 V operation range Low external component cost.
• PLL-based transmitter with frequency range from 300MHz to 1000MHz
• On-chip one-shot circuit
• 60 dB RF on-off ratio for OOK/ASK modulation SOT23-6 package
