CMX808A中文资料Family Radio CTCSS ‘Type 2’ Encoder and Decoder数据手册CML Micro规格书

描述 Description

This device is a unique product for the designer of family radio transceivers. Offering leading edge performance while also being highly cost effective. The device is simple to interface to a host of µControllers via the serial programming interface. A full range of 48 tones can be generated and detected by the device. The decode time has been vastly improved from that offered by other solutions. Fast response and de-response gives the user of a family radio transceiver faster switching times and a reduction in the annoying squelch tail often found in CTCSS b systems. The device has very low power consumption operating at a minimum of 3.0V.
