37 / 68 page [AK5554] 015099864-E-00 2016/03 - 37 - Cascade Connection in TDM mode The AK5554 supports cascade connection in TDM mode. All A/D converted data of connected AK5554 are output from the SDTO1 pin of the last AK5554 by cascade connection. When the ODP pin = “L”, a cascade connection of one devices in TDM128 mode, two devices in TDM256 mode and four devices in TDM512 mode are supported. Figure 29 shows a connection example. When the ODP pin = “H”, a cascade connection of two up to sixteen devices is available. When using multiple devices in slave mode on cascade connection, internal operation timing of each device may differ for one MCLK cycle depending on MCLK and BICK input timings. To prevent this timing difference, BICK “↓” should be more than ± 10ns from MCLK “↑” as shown in Table 10. To realize this timing, BICK divided by two should be input on a falling edge of MCLK as shown in Figure 54 when MCLK=2xBICK (normal speed 1024fs mode). When MCLK=BICK (normal speed 512fs mode), MCLK and BICK should be input in-phase as shown in Figure 55 to satisfy the timing shown in Table 10. 48kHz 256fs 8ch TDM GND LRCK AK5554 #1 BICK TDMIN SDTO1 MCLK LRCK AK5554 #2 BICK TDMIN SDTO1 MCLK 48kHz 512fs 16ch TDM 256fs, 512fs or 1024fs GND LRCK AK5554 #1 BICK TDMIN SDTO1 MCLK LRCK AK5554 #2 BICK TDMIN SDTO1 MCLK LRCK AK5554 #3 BICK TDMIN SDTO1 MCLK LRCK AK5554 #4 BICK TDMIN SDTO1 MCLK TDM256 TDM512 Slave mode Slave mode Master mode Slave mode Slave mode Slave mode Figure 29.
