AK7742
24bit 2ch ADC + 24bit 4ch DAC with Audio DSP
GENERAL DESCRIPTION The AK7742 is a highly integrated audio digital processor, including two stereo 24bit DAC's and one stereo ADC with input selector. The stereo DAC and ADC feature high performance, archiving 106dB and 96dB dynamic range respectively, 8kHz to 96kHz sampling rate are supported. The audio DSP has 1536step/fs parallel processing power, and 74k-bit delay memory allows surround processing, acoustic effect and parametric equalizers. As the AK7742 is a RAM based DSP, it is programmable for user requirements. The AK7742 is available in a space saving small 48pin LQFP package. FEATURES

Each parameter is related to the sampling frequency (fs). HPF response is not included. Note 18. Pass band is from DC to 21.5kHz when fs=48kHz. Note 19. Stop band is from 26.5kHz to 3.0455MHz when fs=48kHz. Note 20. When fs=48kHz, the analog modulator samples the analog input at 3.072MHz. Therefore the input signal is not attenuated by the digital filter in multiple bands (n x 3.072MHz 21.99kHz; n=0, 1, 2, 3 ...) of the sampling frequency.

Note 29. BICK rising edge must not occur at the same time as LRCK edge. Note 30. The serial data output is synchronized to BICK falling edge, and held until next BICK falling (spec -10ns) in Slave mode. In case of the LRCK edge comes before BICK edge, data will be held until LRCK edge (spec -10ns). In Master mode, serial data is held until 30ns before falling edge of BICK. Therefore, please use BICK rising edge in both slave and master modes for a safety latch. .
