Multichannel 96 kHz Codec Data Sheet AD1836A FEATURES APPLICATIONS 5 V multichannel audio system Home theater systems Accepts 16-/18-/20-/24-bit data Automotive audio systems Supports 24-bit and 96 kHz sample rate DVD recorders Multibit - modulators with data directed Set-top boxes scrambling Digital audio effects processors Differential output for optimum performance ADCs: 92 dB THD + N, 105 dB SNR and dynamic range PRODUCT OVERVIEW DACs: 95 dB THD + N, 108 dB SNR and dynamic range The AD1836A is a high performance, single-chip codec that On-chip volume control withauto-ram function provides three stereo DACs and two stereo ADCs using Analog Programmable gain amplifier for ADC input Devices, Inc., patented multibit - architecture. An SPI port Hardware and software controllable clickless mute is included, allowing a microcontroller to adjust volume and Digital de-emphasis processing many other parameters. The AD1836A operates from a 5 V Supports 256 f , 512 f , or 768 f master clock S S S supply, with provision for a separate output supply to interface Power-down mode plus soft power-down mode 2 with low voltage external circuitry. The AD1836A is available in Flexible serial data port with right justified, left justified, I S a 52-lead MQFP (PQFP) package. compatible, and DSP serial port modes TDM interface mode supports 8 in/8 out using a single SHARC SPORT 52-lead MQFP (PQFP) plastic package FUNCTIONAL BLOCK DIAGRAM CCLK CDATA CLATCH COUT MCLK DLRCLK CONTROL PORT CLOCK DBCLK DSDATA1 SERIAL DSDATA2 DATA DSDATA3 I/O VOLUME DAC1L PORT DIGITAL - ALRCLK FILTER DAC ABCLK VOLUME DAC1R ASDATA1 ASDATA2 - DIGITAL VOLUME DAC2L DIGITAL - ADC1L ADC1L FILTER FILTER DAC 48kHz/96kHz 48kHz/96kHz DAC2R VOLUME - DIGITAL ADC1R ADC1R FILTER 48kHz/96kHz 48kHz/96kHz VOLUME DAC3L DIGITAL - CAPL1 FILTER DAC - VOLUME DAC3R ADC2L1 DIGITAL ADC2L PGA FILTER ADC2L2 48kHz 48kHz FILTD CAPL2 CAPR1 - DIGITAL ADC2R1 PGA ADC2R FILTER V REF FILTR ADC2R2 48kHz 48kHz CAPR2 2 432 PD/RST AVDD AGND DVDD DGND Figure 1.
