(see details on jumper settings for j50 in ta b le 7 , ? description of jumper/switch settings, ? on page 7 below.) 3.2. digital i/o and clocks 3.2.1. external i2s interface the steebac9460b evaluation board provides a convenient i2s interface through standard bnc connectors, which allows clock and data signals to be generated by an external source, such as an audio precision test system. to use the bnc inputs for i2s inputs, install jumpers as directed in table 2, ? jumper settings for bnc i2s inputs ? . 3.2.2. i2s clock generation module in addition, the board includes a user-configurable clock generation circuit that pro- vides i2s clock and master clock inputs to the stac9460/61/62/63. to use the clock generation circuit, install jumpers as directed in table 3, ? jumper settings for clk generataion circuit ? . note: when using the clk generation circuit, disconnect any bnc connectors providing clock signals. jumper connections j24 install all jumpers j58 remove all jumpers j62 remove all jumpers table 2. jumper settings for bnc i2s inputs jumper connections j24 install all jumpers j62 remove all jumpers j38 install jumper j54 install jumper 1-2 j56 install jumper 1-2 for 48 khz word clk or install jumper 2-3 for 96 khz word clk j58 install 1-2 for 48 or 96 khz word clk install 5-6 for 3.072 mhz bit clk install 9-10 for 24.5 mhz master clk or install 11-12 for 12.2 mhz master clk install 13-14 to enable bit clk table 3. jumper settings for clk generation circuit

(registers b and d are not printed because they are reserved.) ? rxx ? : reads the value of register xx and prints it out to the screen. ? wxxyy ? : writes value yy into register xx. stac9460/61/62/63 register configuration scripts are provided on the cd-rom included with this evaluation board. these scripts can be used in conjunction with the terminal program to automatically configure the stac9460/61/62/63 for perfor- mance evaluation of the dac or adc. in a typical terminal program, a configuration script can be run automatically by exe- cuting a ? send file ? or ? transfer file ? , creating a fast and convenient method for con- figuring the stac9460/61/62/63. for example, if using hyperterminal, execute transfer, send text file, and then choose the desired stac9460/61/62/63 configu- ration script. this will execute all register writes contained within the chosen config- uration script. see section 6, recommended test procedures, for details on the stac9460/61/62/ 63 configuration scripts. parameter value baud rate 1200 (default) data 8 parity none stop bits 1 flow control off table 6. terminal program configuration

(the signal path for an external loopback test will include the dac.) for an internal loopback test, use the 9460_la2_adc_int_loopback.txt configuration script and the 9460_adc_int_loop_fft.at2c test procedure. for an external loop- back test, use the 9460_la2_adc_ext_loopback.txt configuration script and the 9460_adc_ext_loop_fft.at2c test procedure. use the 9460_adc_thdvampl_sweep.at2c test procedure to perform a sweep of adc thd+n measurements versus input amplitude, in either internal or external loop- back mode. 7. evaluation board schematics the following pages contain schematics for the steebac9460b evaluation board.
