PT4308 pact 433.92 MHz OOK/ASK Receiver DESCRIPTION The PT4308 is a pact, fully integrated OOK ／ ASK receiver with ±4 KV ESD（HBM）protection for 433.92 MHz frequency band and requires few external ponents. The PT4308 consists of a low-noise amplifier （LNA）, an image-rejection mixer（IRM）, a built-in channel-select filter （CSF）, an OOK／ASK demodulator, a data filter, and a data slicing parator. The local oscillator （ LO ） sub-system incorporates a monolithic VCO, a ÷32 feedback divider, a loop filter and a fast start-up reference oscillator to form a plete phase-locked loop-based frequency synthesizer for single channel applications.
