? 12 CXD2720Q-2 description of functions 1. master/slave modes [relevant pins] xmst, lrck, bck when connecting multiple CXD2720Q-2s, or when using as a pair with a d/a converter such as the cxd2558m, one of the CXD2720Q-2 should be in master mode to supply lrck and bck. the clock applied to lrck and bck in slave mode must be synchronized to either the crystal oscillator clock of the xtli and xtlo pins or the external clock input from the xtli pin xmst h l slave mode master mode input output mode lrck, bck i/o 2. master clock system [relevant pins] xtli, xtlo, bfot 768fs (fs = 44.1khz) is assumed for the master clock system, and the connection is as shown below.

? 13 CXD2720Q-2 3. input/output synchronization circuit [relevant pins] lrck, xwo during normal operation, synchronization is performed automatically to input lrck (in slave mode), and phase is matched with serial input data, but if there is a lot of jitter on lrck, or during power input, synchronization may be impossible. in this case, forced synchronization can be done by making the xwo pin low for 2/fs or more. forced synchronization operation is done by the timing of the second lrck rising edge after the xwo pin is made low. when synchronization is completed, return the xwo pin to high. 4. reset circuit [relevant pins] xrst, xtli, xtlo this lsi must be reset after power is turned on. reset is done by making the xrst pin low for 1/fs or more after supply voltage satisfies the recommended operating condition, and the crystal oscillator clock of the xtli, xtlo pins or the external clock input from the xtli pin is correctly applied. 5. serial audio interface (sif) [relevant pins] si, so, bck, lrck, xs24, xmst serial data is used for the external communication of the digital audio data. the CXD2720Q-2 has one system each for input and output, and each one inputs/outputs 2 channels of data at 1 sampling cycles. either the 32-bit clock mode or 24-bit clock mode can be selected. in master mode, the 32-bit clock mode is fixed.

(1) pin structure the five external pins indicated in the table below are allocated for microcomputer interface. microcomputer interface begins operation when xlat is received, so rvdt, trdt, sck and redy are connected in common, and by controlling (wiring) only xlat separately, multiple CXD2720Q-2s can be used. pin name rvdt trdt sck xlat redy i o i i o serial data input from microcomputer. serial data output to microcomputer. high impedance state unless this pin is set to internal data read state by the microcomputer. therefore, it is preferable to perform pull-up or pull- down so that potential is not unstable when this pin is not active. shift clock for serial data. input data from rvdt is taken according to sck rise, and output data from trdt is sent out according to sck fall. interprets the 8 bits of rvdt before this signal rises as transmission mode data, and the bits before that as address data. transmission prohibited while at low level. transmission enabled at high. this pin is an open drain, and must be pulled up externally. i/o function table 6-1. microcomputer interface external pins
? 19 CXD2720Q-2 (2) description of communication formats the data transmission timing between the microcomputer interface and coefficient ram and setup register is called the sv cycle, and is generated once in 1lrck. the sv cycle is generated immediately preceding the signal processing program, so it has absolutely no effect on signal processing, and there is no risk of the sound being cut. in read/write modes, address section + mode section + data section act as one package of data to perform data transmission between the microcomputer and the CXD2720Q-2.

? 21 CXD2720Q-2 (4) details of communication methods the definitions of signal timing required for control from the microcomputer are given below. (4)-1. write first, address section data and mode section data are sent from the microcomputer, synchronized to sck, to the rvdt pin. the address section data is 8 bits both for the coefficient ram and setup register, and the setup register transmits optional data for 1 word length. address section data is sent with lsb first. mode section data is fixed at 8 bits regardless of content. the phase relationship between sck and rv data (data applied to the rvdt pin) has the following restrictions: rv data must be verified before sck rise ( t ds 3 20ns). rv data must be held for 1 t + 20ns or more after sck rise ( t dh ). sck itself has the following restrictions: sck low level must be 1 t + 20ns or more ( t swl ). sck high level must also be 1 t + 20ns or more ( t swh ). after raising sck which corresponds to mode section final data, xlat is raised ( t slp 3 20ns). xlat low level width must be maintained at 1 t + 20ns or more ( t lwl ). further, fall timing restrictions are: for the preceding transmission, if redy falls due to sck, as for write, 3 t + 20ns or more is required. ( t sld ) for the preceding transmission, if redy falls due to xlat, as for read, 20ns or more is required. ( t ldr ) further, if preceding transmissions have been performed and redy = low, it is necessary to wait for redy = high to raise xlat. the procedure until this point is the same for write and read. a 0 r v d t a 7 m 0 m 7 s q 0 0 s q 2 3 a 0 m 7 s c k x l a t r e d y t r d t t d s t d h t s w l t s w h t l s d t s l p t s s t b s p t s l p t s l d t s b d t l d r t r l p t r l p t l w l t l d r t s l d o r t l w h h i g h - z d 0 / s q 0 0 d 1 5 / s q 2 3 figure 6-2. write timing
? 22 CXD2720Q-2 data section write begins after xlat rise, and here also transmission must be with lsb first, with t ds and t dh restrictions. in addition, after raising xlat at the starting point for sending to the data section, wait for 3 t + 20ns or more for the first sck rise. ( t lsd ) when 16 bits (coefficient ram) or 24 bits (setup register) of this write is repeated, redy = low within 4 t + 50ns, and the microcomputer is informed of waiting status for the sv cycle, which is the dedicated data rewrite cycle by microcomputer interface. ( t sbd ) when redy goes high again, the corresponding data is written. the next communication restarts by using the redy signal as follows. when redy = low, the sck for the next transmission can rise ( t bsp 3 20ns ). in the same way, when redy = low, the xlat for the next transmission can fall ( t ldr 3 20ns). redy will fall due to this transmission, but it is prohibited for xlat to rise for the next transmission before the redy rises. be sure to raise the next xlat after redy rises ( t rlp 3 20ns ). in order to restart the next transmission without using the redy signal, the following conditions must be observed: there should be 2 t + 40ns or more left between the sck rise for the final data section and the sck rise for the next transmission ( t ss ). in the same way, the xlat for the next transmission can fall after waiting 3 t + 20ns or more after the final data section sck rise ( t sld ). the t ss and t sld here are shorter times than t sbd 4 t + 50ns, so the restriction conditions are not much strict. however, even in this case the rise of xlat for the next transmission must come after redy rise ( t rlp 3 20ns). further, the restriction for xlat fall at the starting point of this write from t sld can be: t sld 3 3 t + 20ns if the preceding transmission was ?rite?

(vnrpr has the same type of setting as nrpr.) 15 nrpr = dn 2 n?4 n = 2 the expression range for the pitch ratio is: ?.0 nrpr 2.0 ?2 ?2 but for practical use it is: ?.5 nrpr 1.0 or 1 octave. use within a range of half an octave is recommended for quality of sound, although it depends on the aim and the source. also, the algorithm is such that allophones will not be generated even when nrpr setting value is changed. this applies to nrpr_r (rch pitch ratio). (2) l/r common setting and l/r independent setting of pitch ratio the pitch ratio value can be set commonly or independently for lch and rch. it is recommended that the common value be set when the key controller is used as the music key controller, and the independent values be set when it is used as the voice effect. kp (address = 1fh) is used to switch the settings of the common value and independent values. the common value is set when kp is 8000h. nrpr (address = 1dh) is valid, and nrpr_r (address = 1eh) setting value is invalid for both lch and rch in the pitch ratio. the independent values are set when kp is 0000h. nrpr is valid for lch, and nrpr_r is valid for rch in the pitch ratio. (3) notes on key controller off the pitch does not change when nrpr and nrpr_r are set to 0000h (off) when the key controller is off, but depending on the internal state during off, there is no guarantee that the input value will be output as is. during off, after setting nrpr and nrpr_r to 0000h (off), set the pitch control section to through state.
