CMX7164数据手册集成电路（IC）的调制解调器-IC模块规格书PDF

描述 Description

The CMX7164 Multi-mode Wireless Data Modem is a half-duplex device supporting 4/16/32/64 QAM, 2/4/8/16 FSK, GMSK/GFSK and V.23 modes in multiple channel spacings, under host control.
Robust flexible packet data structures including forward error correction and raw data modes are available, supporting user-requirements covering a wide range of applications.
An integrated analogue interface supports direct connection to zero IF I/Q radio transceivers with few external components; no external codecs are required.
Intelligent auxiliary ADC, DAC and GPIO sub-systems perform valuable functions and minimise host interaction and host I/O resources. Two synthesised system clock generators develop clock signals for off-chip use.
The C-BUS/SPI master interface expands host C-BUS/SPI ports to control external devices.
The device utilises CML's proprietary FirmASIC component technology. On-chip sub-systems are configured by a Function Image data file that is uploaded during device initialisation and defines the device's function and feature set.
The devices modulation type is determined by its Function Image (FI) that is uploaded during device initialisation.
The differential inputs are ideal for direct connection to RF Building Block ICs such as CML’s CMX994, CMX994A, CMX994E RF Direct Conversion Receiver ICs
