New 16-Bit 65dB Dynamic Range Standard Voice Codec with DTMF from ChipIdea
This cell (CI7264ia) is a complete 16-bit voice codec instantiated in 0.35m CMOS and retargetable towards any sub-micron CMOS technology with 2.5V/3V/5V supply. It can be used for voice signal processing applications such as mobile telephony, voice recognition, etc It includes 16bit linear A-to-D and D-to-A conversion, channel filtering, microphone amplifier and speaker preamplifier. The A-to-D and D-to-A converters use oversampling delta-sigma technology. The channel filters are implemented digitally, embedded in the decimation and interpolation filters associated with the converters. Dual Transmit volume control has a range of -30/+45 dB with 1 dB steps. The receive volume control has a range of -52/+10 dB with 1 dB, and 6dB steps for the high attenuation range. The preamp ouput can drive 1Kohm/50pF load. The microphone amplifiers have 4 selectable sensitivities.The data port is 16 bits parallel at 8 kHz sample rates. The master clock runs at 2048KHz Multiple power-down modes are included with less than 10mA of standby current. The cell has a 2.7 sqmm analog active area and 40kgate for digital processing.
