    Jumpers and Switches” on page 2-4. Analog Audio Interface For analog audio applications, the Blackfin Audio EZ-Extender uses two AD1938 multichannel 192 kHz audio codecs. The AD1938 is a high-performance, single-chip codec chip that provides four analog-to-digital converters (ADCs) with differential inputs and eight digital-to-analog converters (DACs) with single-ended outputs.
  • Page 17 Blackfin Audio EZ-Extender Interfaces • At a 48 kHz sample rate, TDM mode allows up to 16 channels of data to be sent from each chip in each direction. Each chip uses four of the 16 input channels and eight of the 16 output channels.

  • Page 18: Digital Audio Interface

    On the Blackfin Audio EZ-Extender, the analog input and outputs are not used. The digital interface can operate at up to a 200 kHz sample rate.
  • Page 19 Blackfin Audio EZ-Extender Interfaces supplies an auxiliary serial port for connecting to other devices. The con- figuration registers are configured using an SPI port connected to the processor. The ADAV801 chip provides two internal PLLs, which can produce all necessary internal clocks for the chip interfaces. An external 27 MHz oscillator is used as a clock source for the PLLs.
