PT4316
Description
The PT4316 is a very low power consumption single chip OOK/ASK superheterodyne receiver for the 315 MHz and 434 MHz frequency bands, which offers a high level of integration and requires few external components. The PT4316 consists of a low-noise amplifier (LNA), mixer, SAW-based local oscillator, on-chip Sallen-Key low-pass filter, intermediate frequency (IF) limiting amplifier stage with received-signal-strength indicator (RSSI), and analog baseband data recovery circuitry (data filter, peak detector, and data slicer).
Key Features
- Low current consumption (4.2 mA at VDD = 3.0 V) 2.4 V to 3.6 V supply voltage operation range Optimized for 315 MHz or 434 MHz ISM Band Saw-based oscillator with low frequency drift High dynamic range with on-chip AGC Power down mode with very low supply current (< 1 µA)
- Low external parts count
- Available in 16-pin SOP or SSOP package
