常备现货 普诚 PT4306 全集成OOK/ASK接收机
DESCRIPTION
The PT4306 is a compact, fully integrated OOK/ASKreceiver with ±4 KV ESD (HBM) and ±1 KV ESD (CDM)protections for 433.92 MHz frequency band, and justrequires few external components. The PT4306 consists ofa 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, ÷32feedback divider, loop filter and fast start-up referenceoscillator to form a complete phase-locked loop-basedfrequency synthesizer for single channel applications.
The PT4306 is available in an 8-pin SOP package and isspecified over the temperature range from –40 to +85 °C.
