General Description
The MICRF620 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
European
Telecommunication
Standard Institute (ETSI) specification, EN300 220.
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 be found on Micrel’s web site at:
