• Manufacturer Part Number: ak4683
• Description: Asynchronous Multi-channel Audio Codec With Dir/t
• Manufacturer: AKM Semiconductor, Inc.

(Ta=25°C; AVDD1, AVDD2, DVDD, PVDD, HVDD=4.5∼5.5V; TVDD=2.7∼5.5V; C
Note 18. SDTOA is specified against OLRCKA, SDTIA1-3 are measured against ILRCKA.
Note 19. When MCKO1-0 bits = “01”, “10” or MCKO1-0 bits = “00” and CKSDT bit = “0”.
Note 20. When MCKO1-0 bits = “00” and CKSDT bit = “1” and the EXTCLK is selected by CM1-0 bits.
Note 21. “L” time at I
Note 22. The AK4683 can be reset by bringing PDN “L” to “H” upon power-up.
Note 23. These cycles are the number of LRCKA (LRCKB) rising from PDN rising.
