DESCRIPTION

· The AK4114 is a digital audio transceiver supporting 192kHz, 24bits.

· It supports both consumer and professional modes.

· Automatically detects Non-PCM bit streams.

· Combined with multi-channel codecs (AK4527B or AK4529), it provides a system solution for AC-3 applications.

· Mode setting can be controlled via dedicated pins or a serial µP I/F.

· Compact 48pin LQFP package saves system space.

FEATURES

· Compatible with AES3, IEC60958, S/PDIF, EIAJ CP1201.

· Low jitter Analog PLL with a lock range of 32kHz to 192kHz.

· Clock source: PLL or X'tal.

· 8-channel receiver input and 2-channel transmission output.

· Auxiliary digital input and de-emphasis for multiple frequencies.

· Detection functions include Non-PCM, DTS-CD, sampling frequency, unlock & parity error, and validity flag.

· Supports up to 24bit audio data format.

· Audio I/F: Master or Slave Mode.

· Includes 40-bit channel status buffer, burst preamble bit buffer, and Q-subcode buffer.

· Serial µP I/F and two master clock outputs.

· Operating voltage: 2.7 to 3.6V with 5V tolerance.

· Temperature range: -10 to 70 °C.

APPLICATIONS

· Ideal for AC-3 applications when paired with multi-channel codecs.

· Suitable for systems requiring high-quality digital audio transceiving.

· Compact design fits space-constrained systems.
