ALC882 series datasheet 7.1+2 channel high definition audio codec 15 track id: jatr-1076-21 rev. 1. 5 7.2.4. inbound frame ? multiple sdi a codec can deliver data to the controller on multiple sdis to achieve higher bandwidth. if an inbound stream exceeds the data transfer limits of a single sdi, the codec can divide the data onto separate sdi signals, each of which operate independently, with diff erent stream numbers at the same frame time. this is similar to having multiple codecs connected to the controller. the c ontroller samples the divided stream into separate memory with multiple dma descriptors, then software re-combines the divided data into a meaningful stream. response stream sdi 0 sync stream 'x' frame sync sdi 1 0s tag a stream a, b, x, and y are inde pendent and have separate ids data a tag b data b codec drives sdi 0 and sdi 1 stream 'a' stream 'b' response stream 0s stream 'y' figure 12. codec transmits data over multiple sdi 7.2.5. variable sample rates the hda link is designed for sample rates of 48khz. vari able rates of sample are delivered in multiple or sub-multiple rates of 48khz. two sample blocks per frame result in a 96khz delivery rate, one sample block over two frames results in a 24khz delivery rate . the hda specification states that the sample rate of the outbound stream be synchronized by the contro ller, not by the codec. ea ch stream has its own sample rate, independent of any other stream. the hda controller supports 48khz and 44.1khz base rates. table 7, page 16, shows the recommended sample rates based on multiples or sub-multiples of one of the two base rates. rates in sub-multiples (1/n) of 48khz are interleaving n frames containing no sample blocks. rates in multiples (n) of 48khz contain n sample blocks in a frame. table 8, page 16, shows the delivery cadence of variable rates based on 48khz. the hda link is defined to operate at a fixed 48khz frame rate. to deliver samples in (sub) multiple rates of 44.1khz, an appropriate ratio between 44.1khz and 48khz mu st be maintained to avoid frequency drift. the appropria te ratio between 44.1khz and 48kh z is 147/160. meaning 147 sample blocks are transmitted every 160 frames. the cadence ?12-11-11-12-11-11-12-11-11- 12-11-11-11- (repeat)? interleaves 13 frames containing no sample blocks in every 160 frames. it provides a low long-term frequency drift for 44.1khz of delivery rate. rates in sub-multiples (1/n) of 44.1khz also follow this cadence and interleave n empty frames. rates in multip les (n) of 44.1khz applying this cadence contain n sample blocks in the non-empty frame and interleave an empty frame between non-empty frames (table 9, page 17). www.datasheet.co.kr datasheet pdf - http://www..net/
