● Fully integrated PLL with low phase noise VCO, PLL loop filter and full support of multi-channel operation with arbitrary

channel distance due to fractional-N synthesizer

● Sophisticated threshold control and quasi-peak detector circuit in the data slicer

● 433.92MHz, and 315MHz without external VCO and PLL components

● Efficient XTO start-up circuit (> –1.5k worst case start impedance)

● Changing of modulation type ASK/FSK and data rate without component changes to allow different modulation schemes in

TPM and RKE

● Minimal external circuitry requirements for complete system solution

● Adjustable output power: 0 to 10dBm adjusted and stabilized with external resistor, programmable output power with 0.5dB

steps with internal resistor

● Clock and interrupt generation for microcontroller

● ESD protection at all pins (±2.5kV HBM, ±200V MM, ±500V FCDM)

● Supply voltage range: 2.15V to 3.6V or 4.4V to 5.25V

● Typical power-down current < 10nA

● Temperature range: –40°C to +105°C

● Small 7mm  7mm QFN48 package

Applications

● Automotive keyless entry and passive entry go (handsfree car access)

● Tire pressure monitoring systems

● Remote control systems

● Alarm and telemetering systems

● Energy metering

● Home automation

Benefits

● No SAW device needed in key fob designs to meet automotive specifications

● Low system cost due to very high system integration level

● Only one crystal needed in system

● Less demanding specification for the microcontroller due to handling of power-down mode, delivering of clock and

complete handling of receive/transmit protocol and polling

● Single-ended design with high isolation of PLL/VCO from PA and the power supply allows a loop antenna in the key fob to

surround the whole application

● Integration of tire pressure monitoring, passive entry and remote keyless entry
