PT4308

Compact 433.92 MHz OOK/ASK Receiver

DESCRIPTION

FEATURES



Normal operating of 4.3 mA at 433.92 MHz

Requires few external components

Achieves sensitivity of –114 dBm （peak ASK

signal level）

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



Supply voltage range: 2.1 to 5.5 V

Supports data rates up to 10 Kb／s

Wide input dynamic range with automatic gain

control handling

（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.



Image-rejection ratio of 25 dB

ESD protection level up to ±4 KV for HBM, ±400

V for MM and ±1 KV for CDM

The PT4308 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 standards
