MICRF505 850MHz and 950MHz ISM Band Transceiver General Description RadioWire? The MICRF505 is a true single-chip, frequency shift keying (FSK) transceiver intended for use in half- Features duplex, bidirectional RF links. The multi-channeled ? True single chip transceiver FSK transceiver is intended for UHF radio ? Digital bit synchronizer equipment in compliance with the North American Federal Communications Commission (FCC) part ? Received signal strength indicator (RSSI) 15.247 and the European Telecommunication ? RX and TX power management Standard Institute (ETSI) specification, EN300 220. ? Power down function The transmitter consists of a PLL frequency ? Reference crystal tuning capabilities synthesizer and power amplifier. The frequency ? Frequency error estimator synthesizer consists of a voltage-controlled oscillator (VCO), a crystal oscillator, dual modulus prescaler, ? Baseband shaping programmable frequency dividers, and a phase- ? Three-wire programmable serial interface detector. The loop-filter is external for flexibility and ? Register read back function can be a simple passive circuit. The output power of the power amplifier can be programmed to seven levels. A lock-detect circuit detects when the PLL is Applications in lock. In receive mode, the PLL synthesizer ? Telemetry generates the local oscillator (LO) signal. The N, M, ? Remote metering and A values that give the LO frequency are stored in the N0, M0, and A0 registers. ? Wireless controller The receiver is a zero intermediate frequency (IF) ? Remote data repeater type which makes channel filtering possible with low- ? Remote control systems power, integrated low-pass filters. The receiver ? Wireless modem consists of a low noise amplifier (LNA) that drives a ? Wireless security system quadrature mix pair. The mixer outputs feed two identical signal channels in phase quadrature. Each channel includes a pre-amplifier, a third order Sallen-Key RC low-pass filter that protects the following switched-capacitor filter from strong adjacent channel signals, and a limiter. The main channel filter is a switched-capacitor implementation of a six-pole elliptic low pass filter. The cut-off frequency of the Sallen-Key RC filter can be programmed to four different frequencies: 100kHz, 150kHz, 230kHz, and 340kHz. The I and Q channel outputs are demodulated and produce a digital data output. The demodulator detects the relative phase of the I and the Q channel signal. If the I channel signal lags behind the Q channel, the FSK tone frequency is above the LO frequency (data '1'). If the I channel leads the Q channel, the FSK tone is below the LO frequency (data '0'). The output of the receiver is available on the DataIXO pin. A receive signal strength indicator (RSSI) circuit indicates the received signal level. All support documentation can be found on Micrel?s web site at www.micrel.com.

A lock-detect circuit detects when the PLL is Applications in lock. In receive mode, the PLL synthesizer ? Telemetry generates the local oscillator (LO) signal. The N, M, ? Remote metering and A values that give the LO frequency are stored in the N0, M0, and A0 registers. ? Wireless controller The receiver is a zero intermediate frequency (IF) ? Remote data repeater type which makes channel filtering possible with low- ? Remote control systems power, integrated low-pass filters. The receiver ? Wireless modem consists of a low noise amplifier (LNA) that drives a ? Wireless security system quadrature mix pair. The mixer outputs feed two identical signal channels in phase quadrature. Each channel includes a pre-amplifier, a third order Sallen-Key RC low-pass filter that protects the following switched-capacitor filter from strong adjacent channel signals, and a limiter. The main channel filter is a switched-capacitor implementation of a six-pole elliptic low pass filter. The cut-off frequency of the Sallen-Key RC filter can be programmed to four different frequencies: 100kHz, 150kHz, 230kHz, and 340kHz. The I and Q channel outputs are demodulated and produce a digital data output. The demodulator detects the relative phase of the I and the Q channel signal. If the I channel signal lags behind the Q channel, the FSK tone frequency is above the LO frequency (data '1'). If the I channel leads the Q channel, the FSK tone is below the LO frequency (data '0'). The output of the receiver is available on the DataIXO pin. A receive signal strength indicator (RSSI) circuit indicates the received signal level. All support documentation can be found on Micrel?s web site at www.micrel.com.

The MICRF505 is a true single-chip, frequency shift keying (FSK) transceiver intended for use in half- Features duplex, bidirectional RF links. The multi-channeled ? True single chip transceiver FSK transceiver is intended for UHF radio ? Digital bit synchronizer equipment in compliance with the North American Federal Communications Commission (FCC) part ? Received signal strength indicator (RSSI) 15.247 and the European Telecommunication ? RX and TX power management Standard Institute (ETSI) specification, EN300 220. ? Power down function The transmitter consists of a PLL frequency ? Reference crystal tuning capabilities synthesizer and power amplifier. The frequency ? Frequency error estimator synthesizer consists of a voltage-controlled oscillator (VCO), a crystal oscillator, dual modulus prescaler, ? Baseband shaping programmable frequency dividers, and a phase- ? Three-wire programmable serial interface detector. The loop-filter is external for flexibility and ? Register read back function can be a simple passive circuit. The output power of the power amplifier can be programmed to seven levels.
