Features

• Low cost single conversion superheterodyne receiver architecture
• Compatible with rfPIC™ and rfHCS series of RF transmitters
• Easy interface to PICmicro® microcontroller (MCU) and KEELOQ® decoders
• VCO phase locked to quartz crystal reference: - Narrow receiver bandwidth - Maximizes range and interference immunity
• Selectable LNA gain control for improved dynamic range
• Selectable IF bandwidth via external ceramic IF filter
• Received Signal Strength Indicator (RSSI) for signal strength indication (FSK, FM) and ASK demodulation
• FSK/FM quadrature (phase coincidence) detector demodulat.
