Product details

Description

The TH71112 receiver IC consists of the following building blocks: " PLL synthesizer (PLL SYNTH) for generation of the first and second local oscillator signals LO1 and LO2 " Parts of the PLL SYNTH are the high-frequency VCO1, the feedback dividers DIV_16 and DIV_2, a phase-frequency detector (PFD) with charge pump (CP) and a crystal-based reference oscillator (RO) " Low-noise amplifier (LNA) for high-sensitivity RF signal reception " First mixer (MIX1) for down-conversion of the RF signal to th

Features

! Double superhet architecture for high degree of image rejection ! FSK for digital data and FM reception for analog signal transmission ! FM/FSK demodulation with phase-coincidence demodulator ! Low current consumption in active mode and very low standby current ! Switchable LNA gain for improved dynamic range ! RSSI allows signal strength indication and ASK detection ! Surface mount package LQFP32 Ordering Information Part No. TH71112 Temperature Range -40 °C to 85°C Package LQFP32 Applica.
