Product Description

General Description

The CY620R is a compact, fully integrated OOK/ASK receiver for 433.92 MHz frequency band. It requires few external components. The CY620R consists of a low-noise 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 CY620R is available in an 8-pin SOP package and is specified over the temperature range from -20 to +70 °C.
