PT4304

Fully Integrated OOK/ASK Receiver

DESCRIPTION

FEATURES

The PT4304 is a fully integrated OOK/ASK receiver for the

315 / 433.92 MHz frequency bands requiring few external

components. The PT4304 receiver chain 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



Covers 315 and 433.92 MHz frequency bands

Low power consumption: 4.3 mA for 315 MHz

band and 4.6 mA for 433.92 MHz band under

normal operating conditions



Requires few external components

Achieves excellent sensitivity on the order of –114

dBm for 315 MHz band and –112 dBm for 433.92

MHz band (peak ASK signal level)

feedback divider, loop filter and fast start-up reference

oscillator to form a complete phase-locked loop-based

frequency synthesizer for single channel applications. The

PT4304 also includes an on-chip voltage regulator.



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

The PT4304 is available in a 16-pin SSOP 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
