General Description
This product is Digital-To-Analog Converter for digital audio System (CDP). The product contains Serial-to-Parallel Converter and Compensation Filter, Digital Volume Attenuator by the MICOM Interface, De-Emphasis Filter, FIR filter, Sinc Filter, digital sigma-delta modulator, analog postfilter, AIF (Anti-Image-Filter). The normal input and output channels provides 95dB SNR (Signal to Noise Ratio) over in band (20kHz). The product employs the 1bit 4th-order sigma-delta architecture with 16bit resolution, over sampling of 64X. And analog postfilter with low clock sensitivity and linear phase, filters the shaping-nosie and outputs analog voltage with high resolution. An on-chip reference voltage is included to allow single supply operations.
-16bit Digital-To-Analog Converter -On-Chip Analog Postfilter -Filtered Line-Level Outputs, Linear Phase Filtering -On-Chip Voltage Reference -95dB SNR -Sampling Rate 32KHz/44.1kHz/48KHz -Input Rate 1Fs or 2Fs by Normal Mode/Double Mode Selection -Zero Input Detection Mute -On-Chip Compensation Filter -Input Volume Attenuator by the MICOM Interface -On-Chip De-Emphasis Filter (32KHz/44.1KHz/48KHz) -On-Chip 4 times oversampling Digital Filter -Low Clock Jitter Sensitivity -Single 5V Power Supply

Thes e are test pins for internal block s of the core. So you don't need the internal tes t mode. Make the test control pins disable ('L') state and Output and bidirectional pins leave foalting.
Embedded Core User Guide
- Digital serial data input and clock input refer to digital input format.
- Digital control pins inform refer to pin description. - Micom I/F pin inform refer to micom interface. IDNUM are ID number setting pins for micom Interface. - External application of analog output pins refer to application circuit. - If you want to test only embedded analog core block (Sigma-Delta DAC), you can do it just adding the 4 pins to supply digital serial input data (LRCK, BCK, SDATA, MSCK) and MUX block. - Analog power(VDDA,VSSA,VBB) and digital power(VDDD, VSSD) should be seperated. - VBB pin should be connected to analog ground. - Two pads should be dedicated to analog power(VDDA, VSSA) - If you need not use test mode for the testability of internal core block, you make internal core block test pins disable state. (Test Input pins are 'L' state and Test output, bidirection pins leave floating)
