AKM Semiconductor, Inc. Audio Special Purpose - AK4113VF AK4113VF

The AK4113VF is a 24-bit stereo digital audio receiver designed for high-performance audio applications. It supports sampling rates up to 216kHz and is compatible with various audio formats including AES/EBU, IEC60958, S/PDIF, and EIAJ CP1201. The device features a low jitter analog PLL with a lock range from 8kHz to 216kHz, and it can automatically detect non-PCM bit streams such as Dolby Digital and MPEG. This receiver includes a 6-channel input and a 1-channel transmission output, along with an auxiliary digital input. It offers multiple detection functions, including sampling frequency detection across a wide range of rates, and supports de-emphasis for standard audio frequencies. The AK4113VF operates with a voltage range of 2.7 to 3.6V and is packaged in a compact 30-pin VSOP, making it suitable for space-constrained applications. Its control can be managed via a microprocessor or pin strapping, providing flexibility in integration.
