192KHz / 24 bits up-sampling rate converter

how long would you take to develop this product?

which chips are you going to use?

Quick! I may consider it in CDPRO2!

Proposed upsampler system achitecture:

If put in CD, then 44.1k IIS in, 96K SPDIF out.

If put in DAC, then SPDIF in, IIS 196k direct output to DAC, certainly the clock of upsampler is from DAC.

It is best to design the upsampler to suit both modes and let users decide where to locate the upsampler. You will have more customers.

(1) most prefer.
(2) kept as additional features.
(3) best for actual product in the market ?
(4) good for your upcoming transport course.
