... P.O. Box 17847, Austin, Texas 78760 (512) 445 7222 FAX: (512) 445 7581 http://www.cirrus.com Description The CDB43L43 evaluation board is an excellent means for quickly evaluating the CS43L43 24-bit, stereo D/A converter. Evaluation requires an analog signal analyz- er, a digital signal source for controlling the CS43L43 (for control port mode only) and a power sup- ply. Analog headphone outputs are provided via a 1/8” ...

... CDB43L43 SYSTEM OVERVIEW The CDB43L43 evaluation board is an excellent means of quickly evaluating the CS43L43. The CS8415A digital audio interface receiver provides an easy interface to digital audio signal sources in- cluding the majority of digital audio test equip- ment. The evaluation board also allows the user to supply clocks and data through a 10-pin header for system development ...

... R31 has been changed from a pull- pull- down Mohm pull-down has been added to U10 pin 8, located near R24. The CDB43L43 was also modified to reflect the ® Transient Control changes made to the CS43L43 in Revision G. The second circuit in Figure 3, page 8 of this datasheet was removed, and the CS43L43 Revision G is mounted on the CDB43L43 for evaluation ...
