Brief 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 deresponse gives the user of a family radio transceiver faster switching times and a reduction in the annoying squelch tail often found in CTCSS based systems. The device has very low power consumption operating at a minimum of 3.0V.
