PT4305 Datasheet | PTC

Preliminary 315 MHz / 433.92 MHz PLL Tuned Low Power FSK Receiver DESCRIPTION The PT4305 is a PLL-tuned FSK receiver for short-range wireless data applications in the 315 MHz and 434 MHz frequency bands. The PT4305 offers a high level of integration and only requires few external ponents. The PT4305’s receive section includes a low-noise amplifier, image-reject mixer, IF band-pass filter, limiting amplifier, and frequency-shift keying (FSK) demodulator and also includes automatic gain control (AGC). A switched-capacitor data filter further filters the signal after the demodulator before a slicing parator restores the data to full-swing CMOS logic levels. The local...
