PT4307 Compact 315 MHz OOK/ASK Receiver DESCRIPTION FEATURES The PT4307 is a compact, fully integrated OOK/ASK Normal operating of 4.3 mA at 315 MHz receiver with 4 KV ESD (HBM) and 1 KV ESD (CDM) Requires few external components protections for 433.92 MHz frequency band, and just Achieves sensitivity of 114 dBm (peak ASK requires few external components. The PT4307 consists of signal level) a low-noise amplifier (LNA), image-rejection mixer (IRM), Supply voltage range: 2.4 to 5.5 V built-in channel-select filter (CSF), OOK/ASK demodulator, Supports data rates up to 7.2 Kb/s data filter, and data slicing comparator. The local oscillator Wide input dynamic range with automatic gain (LO) sub-system incorporates a monolithic VCO, 32 control handling feedback divider, loop filter and fast start-up reference Image-rejection ratio of 25 dB oscillator to form a complete phase-locked loop-based ESD protection levels up to 4 KV HBM, 400 V frequency synthesizer for single channel applications. MM and 1 KV CDM The PT4307 is available in an 8-pin SOP package and is specified over the temperature range from 40 to +85 C. APPLICATIONS Automotive Remote Keyless Entry (RKE) Remote control Garage door and gate openers Suitable for applications that must adhere to either the European ETSI-300-220 or the North American FCC (Part 15) regulatory standard.

L1 and C1 are the components for input matching network. They may need to be adjusted for different PCB layout and antenna requirements. 2. The value of C4 depends upon the data rate and coding pattern. 3. The optional components may be used depending upon specific application requirements, e.g. C5 can be removed if the crystal oscillator operates at the accurate frequency. V1.0 2 June 2016
