S5L9250B data sheet 154 block description the goal of the digital audio interface block is to transmit the data in the cd disc serially into the surrounding systems. this interface method has the advantage of needing only one pin for transmission. in other words, there are no additional pins needed such as separate clocks. because of this advantage, it is utilized not only in audio systems for home use, but also for professional use. subframe 1 frame 191 subframe 2 frame 0 frame 1 start of block x channel 1 y channel 1 z channel 1 y channel 1 x channel 1 y channel 1 spdif (sony- philiiips digital audio interface) this interface is called spdif because sony and philips came up with the digital audio interface method for cds, and its regulations are registered in the aes (audio engineering society). spdif serially transmits data and is sensitive to background noise. to overcome this disadvantage, the digital out data is transmitted after being demodulated into biphase form. phase0 is given a different value from the previous data's phase1 value. if the source data is '0', phase1 is given the same value as phase0, and if it is '1', phase1 is given a different value from phase0. aux data preamble valid data audio data user data channel status parity data preamble aux audio data lsb msb v u c p 3 4 7 8 27 28 30 29 31 0 structure of format each subframe is configured of 32 time slots, and a subframe includes audio data. 2 subframes make 1 frame, which as left, right stereo signal components. 192 frames make 1 block, which is the control bit information unit. bit0 bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit28 bit29 bit30 bit31 bit24 bit25 bit26 bit27 bit n fs = 44.1 khz 128 fs source coding .... digital audio out channel coding (biphase mark) preamble z
data sheet S5L9250B 155 subframe format preamble (4 bit) : the preamble has the sync data of each subframe and block, and preamble data is not converted into biphase signal to maintain the sync data's uniqueness. however, it starts with the opposite value of the previous symbol's phase1 value. the preamble needs three patterns to tell apart left, right, and the beginning of a block, which are shown below. preceding state 0 1 channel coding "x" 11100010 00011101 subframe 1 "y" 11100100 00011011 subframe 2 "z" 11101000 00010111 subframe 1 and block start preamble 'x' is channel 1's sync., and preamble 'y' is channel 2's sync. preamble 'z' is used to show the block's start sync. the reason why there are two sync patterns for each preamble is because the value is reversed according to the phase of the previous data. 2) aux (4 bits) : auxiliary data area. 3) audio data (20 bits) : although the resolution of the audio data transmitted to digital out for cds is 16 bits, it can be 20 or 24 bits by augmenting the audio data area to the aux area. this are is lsb first. 4) validity bit (1 bit) : if studio sample word can be converted into analog audio signal, validity bit is set to '1'. if not, it is set to'0'. in the case of cds, it is set to'0'. 5) user data (1 bit) : cds use this area to transmit subcode data. 6) control status data (1 bit) : data is input by each subframe, and 192 subframes make one control status data. there are the consumer mode and professional mode in this area, and the 4th generation cdp supports consumer mode. for cds, control status data has the following meaning. bit description 0 0 : consumer use, 1 : professional use 1 0 : normal audio, 1 : nonaudio mode 2 0 : copy prohibit, 1 : copy permit 3 0 : no preemphasis, 1 : preemphasis 4 reserved (= 0) 5 0 : 2 channel, 1 : 4 channel 6 - 7 00 : mode 0, reserved 8 - 15 10000000 : 2 channel cd player user bit channel = cd subcode bit optional 16 - 19 source number ( = 0000) 20 - 23 channel number ( = 0000) 24 - 27 sampling frequency : 44.1khz = 0000 28 - 29 clock accuracy 00 : normal accuracy, 10 : high accuracy, 01 : variable speed 30 - 191 don't care ( all zero )
