General Description

The MICRF600 is a self-contained frequency shift keying (FSK)

transceiver module, intended for use in half-duplex, bidirectional

RF links. The multi-channeled FSK transceiver module is intended

for UHF radio equipment in compliance with the North American

Federal Communications Commission (FCC) part 15.247 and

249.

The transmitter consists of a fully programmable PLL frequency

synthesizer and power amplifier. The frequency synthesizer

consists of a voltage-controlled oscillator (VCO), a crystal

oscillator, dual modulus prescaler, programmable frequency

dividers, and a phase-detector. The output power of the power

amplifier can be programmed to seven levels. A lock-detect circuit

detects when the PLL is in lock.

In receive mode, the PLL synthesizer generates the local oscillator

(LO) signal. The N, M, and A values that give the LO frequency

are stored in the N0, M0, and A0 registers.

The receiver is a zero intermediate frequency (IF) type that makes

channel filtering possible with low-power, integrated low-pass

filters. The receiver consists of a low noise amplifier (LNA) that

drives a 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 350kHz. 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, then 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
