315/433MHz Receiver
The
heterodyne receiver IC is designed for applications in the
European 433 MHz industrial-scientific-medical (ISM)
band, according to the EN 300 220 telecommunications
standard. It can also be used for any other system with
carrier frequencies ranging from 300 MHz to 450 MHz
(e.g. for applications according to FCC part 15 and ARIB
STD-T67).
Features
• Single-conversion superhet architecture for low external component count
• FSK for digital data and FM reception for analog signal transmission
• FSK/FM 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
• 32-pin Low profile Quad Flat Package (LQFP32)
Technical Data Overview
• Input frequency range: 300 MHz to 450 MHz
• Power supply range: 2.3 V to 5.5 V @ ASK
• Temperature range: -40 °C to +85 °C
• Standby current: 50 nA
• Operating current: 6.5 mA at low gain mode
• Sensitivity: -113 dBm @ ASK, 180 kHz IF filter BW
• Range of IF: 400 kHz to 22 MHz
• Maximum data rate: 260 kbps NRZ @ ASK
• Image rejection: > 45 dB (e.g. with SAW front-end filter and at 10.7 MHz IF)
• Maximum input level: -10 dBm at ASK
• Spurious emission: < -70 dB
• Input frequency acceptance: up to ±100 kHz
• RSSI range: 70 dBm
• FM/FSK deviation range: ±2.5 kHz to ±80 kHz
• Maximum analog modulation frequency: 15 kHz
