Description
The PT4316 is a high performance 315/433 MHz ASK/OOK receiver for the Remote
Keyless Entry (RKE) systems. The chip consists of a LNA, mixer, integrated IF filter,
limiter, data filter, data slicer, peak detector and SAW oscillator.
Features
Supply voltage: 2.4V to 3.6V
Frequency range: 250MHz to 500MHz, depend on the external SAW resonator.
Sensitivity: -103dBm
Current consumption: 4mA
Data rate: 10Kbps maximum
High dynamic range with on-chip AGC
