1. DESCRIPTION
The MRF600R/MRF610R is a fully integrated OOK/ASK receiver for the 315 / 433.92 MHz frequency bands requiring few external components.
The MRF600R/MRF610R receiver chain consists of a lownoise amplifier (LNA), image-rejection mixer (IRM), built-in channel-select filter (CSF), OOK/ASK demodulator, data filter, and data slicing comparator. The local oscillator (LO) sub-system incorporates a monolithic VCO, ÷ 32 feedback divider, loop filter and fast start-up reference oscillator to form a complete phase-locked loop-based frequency synthesizer for single channel applications. The MRF600R/MRF610R also includes an on-chip voltage regulator.
The MRF600R/MRF610R is available in a 16-pin SSOP/SOP package and is specified over the temperature range from –40 to +85 °C.
