TH7111

868/915MHz

FSK/FM/ASK Receiver

Features

! Double superhet architecture for high degree of image rejection

! FSK for digital data and FM reception for analog signal transmission

! FM/FSK demodulation either with phase-coincidence or PLL demodulator

! Low current consumption in active mode and very low standby current

! Switchable LNA gain for improved dynamic range

! AFC feature allows wide carrier frequency acceptance range

! RSSI allows signal strength indication and ASK detection

! Surface mount package LQFP44

Technical Data Overview

! Input frequency range: 800 MHz to 930 MHz

! Power supply range: 2.5 V to 5.5 V for double conversion and 3.3 V to 5.5 V for single conversion

! Temperature range: -40 °C to +85 °C

! Operating current: 7.5 mA at low gain and 9.2 mA at high gain mode

! Standby current: < 100 nA

! Sensitivity: -109 dBm ¹⁾with 40 kHz second IF filter BW (incl. SAW front-end filter loss)

! Sensitivity: -102 dBm ²⁾with 150 kHz second IF filter BW (incl. SAW front-end filter loss)

! Range of first IF: 10 MHz to 80 MHz

! Range of second IF: 455 kHz to 21.4 MHz

! Maximum input level: –10 dBm at ASK and 0 dBm at FSK

! Image rejection: > 65 dB (e.g. with SAW front-end filter and at 10.7 MHz 2^ndIF)

! Spurious emission: < -70 dBm

! Input frequency acceptance: ±50 kHz (with AFC option)

! RSSI range: 70 dB

! Frequency deviation range: ±5 kHz to ±120 kHz

! Maximum data rate: 80 kbit/s NRZ

! Maximum analog modulation frequency: 15 kHz

¹⁾at ± 8 kHz FSK deviation, BER = 3 10^-3and phase-coincidence demodulation

²⁾at ± 50 kHz FSK deviation, BER = 3 10^-3and phase-coincidence demodulation
