PCM1702 PDF

BB PCM vs I prefer the as it is easier to implement in a DIY application however I want the best I can get so can anyone provide some advice? I have tested both chips and percieved the to give better low level resolution but in all fairness it was not a completly comparably set up DIY bit clock as compared to a std one and slightly different layout whick is why I am confused, afterall the only datasheet benefit on bit material of the is slightly dB lower THD at 0dB. Besides technical data, PCM is considered to be much better than It was the successor to the famous PCM

Post a comment. Denon must have persuaded Burr-Brown to test a higher grade spec than the datasheet. The datasheet has -J and -K options, but not -L. However they were only going to buy a small number so we said no. Denon would have had much more clout in the late 90s. A few months back I decided to create a hi-fi system in a much bigger room in my house.

Rather than spend another large bunch of money I decided to go for used equipment. I bought a Philips FA amplifier which came out in the 90s. It had superb specs, better than some top end amplifiers in Hi-Fi mags today, and kind of equivalent to the new Marantz UK Edition, but with a bunch of extra features for the time, and more power.

Philips and Marantz were always one and the same anyway. The output buffer amps on the PCMLs are ultra wideband very low noise operational amplifiers from NEC, so you could argue that the noise performance on buffer amps has not yet been beaten. I also looked at the series CD players from Philips from the same era as my FA amp, but the performance was terrible, due primarily to the fact Philips had used their own 1-bit sigma delta DAC, which gave really poor performance.

PCM1702 DAC

I also had positive experience with a PCM circuits which are very similar but they have 24 bits instead 20 in this DAC. Both are R-2R ladder construction that I expected that they will sound similar to other DACs with this construction and it was confirmed. Circuit PCM has 20 bits. With a right timing respectively delaying for 11 bits with IC5 and IC6 circuits we reach that 20 most significant bits of sample will be step by step shifted to the DACs shift register and after that with help of LRCK latch signal written on the output. For guarantee that both channels will be played in a same time we must delay left channel data for 32 bits with IC7 to IC Thank to this will be data sent to the DACs in a same time. Resistors R1 to R3 are for elimination of signal reflections.
