PT4318

Low Power 315/433MHz OOK/ASK

Super-heterodyne Receiver

with SAW-Based Oscillator

DESCRIPTION

FEATURES

The PT4318 is a low power single chip OOK/ASK

super-heterodyne receiver for the 315 MHz and 434



Wide supply voltage range: 2.4 V to 5.5 V

Supports 315 MHz / 434 MHz ISM bands

Low current consumption: 5 mA typ. at 434 MHz

SAW-based oscillator with low frequency drift

Automatic gain control (AGC) function

Auto-tuned on-chip channel select filter

Supports data rates up to 10 Kb/s

MHz frequency bands.

It offers a high level

integration and requires few external components.

The PT4318 is composed of a low-noise amplifier

(LNA),

down-conversion

mixer,

SAW-based

oscillator, auto-tuned on-chip gm-C intermediate

frequency (IF) band-pass filter, IF limiting amplifier

with received-signal-strength indicator (RSSI),

automatic gain control (AGC) circuitry, and analog

baseband data recovery circuitry (data filter, peak

detector, and data slicer).

Requires few external components

16-pin SSOP package

APPLICATIONS



Remote Keyless Entry (RKE) systems

Remote control systems

Garage door openers

Alarm systems

Security systems

Wireless sensors

The PT4318 is available in the 16-pin SSOP package

and operate in a specific temperature range from –40

to +85°C.
