PT4308 Compact 433.92 MHz OOK/ASK Receiver DESCRIPTION The PT4308 is a compact, fully integrated OOK ／ ASK receiver with ±4 KV ESD（HBM）protection for 433.92 MHz frequency band and requires few external components. 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 comparator. 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 complete phase-locked loop-based frequency synthesizer for single channel applications. FEATURES  Normal operating of 4.3 mA at 433.
