Receiver IC


PT4304

The PT4304 is a fully integrated OOK/ASK receiver for the 315 / 433.92 MHz frequency bands requiring few external components. The PT4304 receiver chain 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 PT4304 also includes an on-chip voltage regulator.

The PT4304 is available in a 16-pin SSOP package and is specified over the temperature range from –40 to +85 °C.
