Introduction

The IC is a low power ASK/FSK Receiver for the frequency bands 300 - 320, 425 - 450, 863 - 870 and 902 - 928 MHz. Bi-phase modulation schemes, like Manchester, bi-phase mark, bi-phase space and differential Manchester are supported. The chip offers best-in-class sensitivity performance at a very high level of integration and needs only a few external components. The device is qualified to automotive quality standards and operates between -40 and +105°C at supply voltage ranges of 3.0 - 3.6 Volts or 4.5 - 5.5 Volts. The receiver is realized as a double down conversion super-heterodyne/low-IF architecture each with image rejection supplemented by digital signal processing in the baseband. A fully integrated Sigma-Delta Fractional-N PLL Synthesizer allows for high-resolution frequency generation and uses a crystal oscillator as the reference. The on-chip temperature sensor may be utilized for temperature drift compensation via the crystal oscillator.
