Decoder/post-processor algorithm combination support varies depending upon the chip version and the system configurations. Visit www.analog.com for complete information. 3 The 100-lead and 88-lead packages do not contain an external port. The SDRAM controller pins must be disabled when using this package. For more information, see Pin Function Descriptions on Page 14. The ADSP-21486 processor in the 176-lead package also does not contain a SDRAM controller. For more information, see 176-Lead LQFP_EP Lead Assignment on page 62. 4 Some models have –140 dB performance. For more information, see Ordering Guide on page 70. 5 Only available up to 400 MHz.
