PT4306

Compact 433.92 MHz OOK/ASK Receiver

DESCRIPTION

FEATURES

The PT4306 is a compact, fully integrated OOK/ASK

receiver with ±4 KV ESD (HBM) and ±1 KV ESD (CDM)

protections for 433.92 MHz frequency band, and just

requires few external components. The PT4306 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.



Normal operating of 4.6 mA at 433.92 MHz

Requires few external components

Achieves sensitivity of –112 dBm (peak ASK

signal level)

Supply voltage range: 2.4 to 5.5 V

Supports data rates up to 10 Kb/s

Wide input dynamic range with automatic gain

control handling



Image-rejection ratio of 25 dB

ESD protection levels up to ±4 KV HBM, ±400 V

MM and ±1 KV CDM

The PT4306 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.
