CMX7158数据手册集成电路（IC）的音频专用规格书PDF

描述 Description

The CMX7158 is a full-duplex, frequency inversion audio scrambler IC. This makes it a suitable device for use in multi-function audio systems as well as mobile and hand portable Cellular / Bluetooth / PMR / LMR radio systems.
The device provides additional functionality to facilitate implementation including DTMF and Selcall signalling, VOX detection on both channels and a MIC AGC.
There are flexible power saving modes and the production devices will be supplied as a FirmASIC® Function Image format in a 48-pin VQFN Q3 package suitable for use with the PE0402 evaluation kit.
The device is realised using CML’s proprietary FirmASIC® component technology. A Function Image™ that defines the devices functionality is loaded at power-up, either from a host controller connected over the C-BUS interface or an attached serial flash memory device.
