AKM Releases a High Performance 6-channel, 192 kHz Asynchronous Sampling Rate Converter

Asahi Kasei Microsystems Co., Ltd. (AKM) today introduced the AK4126, a 6-channel, master-clock-free, 24-bit, 192 kHz- asynchronous sampling rate converter for professional audio, DVD recorder and in-car A/V applications.

Based on the popular AK4125 asynchronous sampling rate converter, the new AK4126 features 6 input and 6 output channels. Increasing the input and output channels provides a dependable solution for digital A/V products such as DVD recorders and in-car equipment supporting the MOST standard.

The AK4126’s 6-channel performance meets a variety of multi-channel needs including those for DVD 5.1 surround systems. As a result, in applications where three AK4125s were previously required, one AK4126 can now fully suffice. A huge benefit of the new converter is that it reduces the surface mounting space by as much as 35 percent.

With an impressive 140dB dynamic range, the AK4126 ensures minimal degradation in sampling rate conversion over the range of linear PCM formats on CDs and DVDs. What is more, like the AK4125, the AK4126’s built-in PLL can extrapolate the local master clock from the interface data clock. This eliminates the need for an external master clock and complementing internal circuits. This feature makes the AK4126 ideal in systems that either cannot supply a master clock or systems in which master-clock radiation could impair system performance. In addition, settings such as audio formatting are all pin programmable eliminating the requirement for microprocessor control.

Available in a 64pin LQFP package, AK4126 samples and evaluation boards are available now. To obtain more information, contact AKM, Audio & Video Business Operation, Nishi-Shinjuku 1-23-7, Shinjuku-ku, Tokyo 160-0023, Japan.
