DATASHEET
Advance Information
7163 FI-4.x QAM Modem
Features
 Half-duplex QAM modem supports multiple
modulations and channel spacings
 No DSP or Codecs required; simply upload
modulation Function Image™ (FI)
 QAM 7163 FI-4.x
o 4/16/64 QAM up to 96kbps in 25kHz
o Different rate, robust FEC choices
o Channel estimation and equalisation
o FEC and raw (uncoded) modes
o Two x frame sync detectors
o Automatic frame sync detect
o Formatted blocks for packet construction
o Rx carrier frequency and phase correction
o Receive signal quality measurement
 High Performance I/Q Radio Analogue
Interface
o Tx and Rx: ‘Direct connect’ to zero IF
transceiver
o Simple external RC filters
o Digital IF filter reconfigures for multiple RF
channel spacings (Rx)
o Deviation control without manual trim (Tx)
o I/Q trims
 C-BUS host Serial Interface
o SPI-like with register addressing
o Read/Write 128-byte FIFOs and data buffers
streamline transfers and relax host service
latency
 Auxiliary Functions
o Four x 10-bit DACs
o Autonomous RAMDAC sequencer
o Automatic support for dc calibration of CMX998
o Four x 10-bit ADCs
o ADC averaging and trip on high/low ‘watch’ modes
o Four x GPIO
o Sequence GPIO on Tx or Rx trigger
o Start Tx on digital trigger input
 Master C-BUS/SPI Serial Interface
o For external slave devices e.g. RF transceiver and
synthesiser
o Pass-through mode expands host C-BUS/SPI
capacity
 Two Synthesised Clock Generators
 Low Power 3.3V Operation with Powersave
Functions
 Small 64-pin VQFN and LQFP Packages
Applications
 High Performance Narrowband Data Radio
o Telemetry/SCADA/data modems
o 6.25kHz to 25kHz RF channel spacing
o Compatible worldwide e.g. ETSI, FCC, ARIB, etc.
o FCC Part 90 per new spectral efficiency
requirements
 Digital Software Defined Radio (SDR)
 High-speed Wireless Data
 Mobile Data over Fading Channels
