ALC231 datasheet high definition audio codec with mono class-d speaker amplifier 16 track id: jatr-2265-11 rev. 1.1 7.2.3. 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. each stream has its own sample rate, independent of any other stream. the hda controller supports 48khz and 44.1khz base rates. table 7 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 interleavi ng n frames containing no sample blocks. rates in multiples (n) of 48khz contain n sample blocks in a frame. table 8 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 appropriate ratio betw een 44.1khz and 48khz is 147/160. meaning 147 sample blocks are transmitted every 160 frames. the cadence ?12-11-11-12-11-11-1 2-11-11-12-11-11-11- (repeat)?inte rleaves 13 frames containing no sample blocks in every 160 frames . it provides a low long-term fr equency drift for a 44.1khz delivery rate. rates in sub-multiples (1/n) of 44.1khz also follow this cadence and interleave n empty frames. rates in multiples (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). table 7. defined sample rate and transmission rate (sub) multiple 48khz base 44.1khz base 1/6 8khz (1 sample block every 6 frames) - 1/4 12khz (1 sample block every 4 frames) 11.025khz (1 sample block every 4 frames) 1/3 16khz (1 sample block every 3 frames) - 1/2 - 22.05khz (1 sample block every 2 frames) 2/3 32khz (2 sample blocks every 3 frames) - 1 48khz (1 sample block per frame) 44.1khz (1 sample block per frame) 2 96khz (2 sample blocks per frame) 88.2khz (2 sample blocks per frame) 4 192khz (4 sample blocks per frame) 176.4khz (4 sample blocks per frame) table 8. 48khz variable rate of delivery timing rate delivery cadence description 8khz ynnnnn (repeat) one sample bloc k is transmitted in every 6 frames 12khz ynnn (repeat) one sample block is transmitted in every 4 frames 16khz ynn (repeat) one sample block is transmitted in every 3 frames 32khz y 2 nn (repeat) one sample block is transmitted in every 6 frames 48khz y (repeat) one sample block is transmitted in every 6 frames 96khz y 2 (repeat) two sample blocks are transmitted in each frame 192khz y 4 (repeat) four sample blocks are transmitted in each frame n: no sample block in a frame. y: one sample block in a frame. yx: x sample blocks in a frame. www.datasheet.co.kr datasheet pdf - http://www..net/

ALC231 additional power features the ALC231 is designed to meet intel?s low-powe r-state white paper and is ecr hda-015b compliant. it meets the five attributes discussed in the white paper: 1. d3 state power < 30mw (without pc-beep pass-through function) 2. exit latency (d3 to d0 transfer) < 10ms. 3. audio pop/click suppression during d3 and d0 transition < -65dbv. 4. supports jack detection in d3 state. 5. d3 functions with or without the bitclk the ALC231 minimizes d3 state idle mode power consumption and increases overall battery life in mobile systems. in d3 mode, only a power on reset or a ?double f unction reset? resets all ALC231 settings, cutting software configuration time spent entering/leaving d3 state, and reducing latency time for d3 to d0 transitions. the ALC231 supports wake-up events in d3 mode, incl uding jack detection and gpio status changes. if the hda-link was alive (with bclk), the ALC231 wake-up response is as normal. if no bitclk is present, the ALC231 drives the sdi hi gh in order to wake up the system. www.datasheet.co.kr datasheet pdf - http://www..net/
