ZL49020 General Description

The ZL490xx is a family of high performance DTMF receivers which decode all 16 tone pairs into a 4-bit binary code. These devices incorporate an AGC for wide dynamic range and are suitable for end-to-end signalling. The ZL490x0 provides an early steering (ESt) logic output to indicate the detection .
