(b) A critical component is one whose failure to function or perform may reasonably be expected to result, whether directly or indirectly, in the loss of the safety or effectiveness of the device or system containing it, and which must therefore meet very high standards of performance and reliability. • It is the responsibility of the buyer or distributor of an AKM product who distributes, disposes of, or otherwise places the product with a third party to notify that party in advance of the above content and conditions, and the buyer or distributor agrees to assume any and all responsibility and liability for and hold AKM harmless from any and all claims arising from the use of said product in the absence of such notification. < KM079202> 2006/08 - 25 - 5 4 3 2 1 for 74HC14, 74HCU04, 74LS07, 74HC4040 VDD C1 C2 C3 C4 0.1u 0.1u 0.1u 0.1u + T1 C5 47u LP2950A 3.3V JP1 L1 + 47u IN OUT C7 0.1u 1 1 C8 0.1u 2 C6 D GND REG 3 5V + C9 C10 + 47u D R2 D1 R1 short 10k U1A 1 H L U1B 2 3 74HC14_1 4 PDN 74HC14_1 AVDD C11 SW1 U2 C12 C15 68p C13 10u AVDD + J1 BNC 3.9n C14 0.1u R3 DVDD + C16 10u open C17 0.1u C X1 1 2 FILT TST2 24 TST2 2 AVSS TST1 23 TST1 3 AVDD TSTI2 22 TSTI2 4 SIF TSTI1 21 TSTI1 5 DVSS TSTO 20 6 DVDD PDN 19 0 7 SDTO INT1 18 0 8 SCLK INT0 17 R7 0 9 0 PDN 9 LRCK CAD1 16 CAD1 10 MS CAD0 15 CAD0 11 TDMIN SCL 14 12 MCLK SDA 13 LE1 6 K 74HC14_1 1k U1D R8 A INT1 K 1k 74HC14_1 C LE2 8 A VDD INT0 AK4140 1M U3A 1 R5 U1C 5 R6 R9 R10 1 R4 MS 12.288MHz JP2 DVDD 0.1u AK4140_PDN U3B 2 3 74HCU04 XTL 4 74HCU04 JP3 U4 EXT MCLK C18 10 CLK 11 RST MCLK C19 5p B 2 47u VDD XTE 10u 5p PORT1 10 9 8 7 6 1 2 3 4 5 MCLK BICK LRCK SDTO TDMIN R15 R17 R16 R19 R20 100 100 100 100 100 74HC4040 BICK LRCK SDTI TDMIN Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 Q9 Q10 Q11 Q12 9 7 6 5 3 2 4 13 12 14 15 1 1/2 1/4 4040_BICK JP4 BICK R11 1/256 1/512 4040_LRCK GND JP7 TDMIN 6 7 8 9 10 5 4 3 2 1 TST2 TST1 TSTI2 TSTI1 RP1 470 R21 R22 10k 470 1 U5A 2 74LS07 VDD 10k 100 R14 B R18 3 U5B 4 74LS07 VDD 10k R23 (short) R24 SDA(ACK) 51 16 15 14 13 12 11 10 9 VDD uP-I/F AK4140 9 8 7 6 5 4 3 2 1 A 1 2 3 4 5 6 7 8 10k SCL SDA SDA(ACK) SW2 MS CAD1 CAD0 R13 VDD JP5 LRCK PORT2 EXT R12 MS CAD1 CAD0 A TST2 TST1 TSTI2 TSTI1 47k Title Size AKD4140-A Document Number A3 Date: 5 4 3 2 Friday, April 22, 2005 Rev AK4140 Sheet 1 0 1 of 2 5 4 3 2 1 T2 5V VDD + short C20 47u C21 OUT IN 3 5V + C23 C22 2 1 GND LP2950A R101 0.1u 47u 0.1u D D U6 MCLK U1 24 2 TRANS DIF2 23 3 RESETN DIF1 22 4 MCLK DIF0 21 5 SDTI TXP BICK 6 BICK TXN 19 LRCK 7 LRCK DVSS 18 8 FS0/CSN DVDD 17 FS1/CDTI CKS1 16 CKS0 15 SDTI 4040_BICK C V1 9 4040_LRCK 10 FS2/CCLK PORT3 5V DIT_DIF0 OPT C24 JP6 11 FS3/CDTO BLS 14 12 C1 ANS 13 PM 16 BNC IN VCC IF GND 1k 0.1u 20 C25 0.1u 4 3 2 1 R25 5V + AK4103A_PDN 1 5 5 6 6 TOTX176 TX C26 10u DIT_CKS1 J2 T3 R26 TX0 DA02-F 330 R27 DIT_CKS0 8 4 5 1 1 2 3 4 5 0.1u 100 1:1 C AK4103A U7 1 MCLK 2 BICK DIF1 15 3 SDTI VDD 14 VDD AK4103A_PDN C28 0.1u VDD 4 R28 LRCK VSS 13 B 10k 11 H L U1F 10 13 74HC14_1 + U1E 12 SW3 5 PDN VCOM 12 6 DFS0 LOUT 11 7 DFS1 ROUT 10 8 DEM C30 10u 74HC14_1 C31 DAC/DIT_PDN 10u + D2 C29 R29 J3 220 LOUT R31 J4 220 ROUT C32 0.1u R30 22u AK4386 SW4 DIT_DIF0 DIT_CKS0 DIT_CKS1 DAC_DIF0 1 2 3 4 8 7 6 5 DIF0 9 10k DAC_DIF0 + B + VDD C33 R32 22u 10k DAC/DIT A A RP2 4 3 2 1 DIT_DIF0 DIT_CKS0 DIT_CKS1 DAC_DIF0 Title 47k Size AKD4140-A Document Number A3 Date: 5 4 3 2 Friday, May 27, 2005 Rev DIT/DAC Sheet 1 0 2 of 2
