Hi,
I have measured THD+N, and it looks good (below -93dB as in spec) until around 5kHz, where it starts to increase up to -86dB at 20kHz. Is this normal for the DAC, or the sign of a problem.
Test setup was 24bit, 48kHz, 0dBFS S/PDIF -> DIR9001 …
Other Parts Discussed in Thread: PGA2320 , SRC4192 , PCM4202 , DIR9001 , MUX36S08 , DIT4192 , PCM1794A Hi,
I am using in an application the PCM1794A, PCM4202, DIT4192, several opamps, SRC4192, DIR9001, MUX36S08 and PGA2320 for volume control. Due to…
The DIR9001 doesn't support dual wire mode (this is a band aid legacy mode for effective 192kHz sampling rate using 96kHz equipment) therefore your combination of parts won't work for this mode. You can use some of the more modern native 192kHz capable…
Other Parts Discussed in Thread: TAS5558 , PCM3070 , DIR9001 , TAS5631 , TAS5631B , TAS5614A , TAS5548 , TAS5614LA Hello,
I use a tas5558 with bd modulation (because the outputfilter of my class d amp is designed for bd modulation). Unfortunately there…
Other Parts Discussed in Thread: DIR9001 , TAS5710 , TAS5717 Hi
I am using a TAS5710 (with a DIR9001 to provide clocks and data from an SPDIF source)
I have two problems - which obviously may be related
1) The amplifier only initialises and plays…
Other Parts Discussed in Thread: DIR9001 , PCM1794 , PCM1794A , PLL1708 , TS3L110 Hi,
Im planning to feed my PCM1794A with I2S data. I want to switch the I2S Signal with an 74HC157D 2-input multiplexer. As far as I see the PCM1794 uses the clock source…
Other Parts Discussed in Thread: PCM4222 , DIR9001 Dear TI Team,
I'm currently building a small audio mixer based on an I2S capable DSP. The audio mixer integrates different IC that are all delivering digital audio via I2C bus in 48 KHz sampel rate…
Part Number: PROCESSOR-SDK-AM335X
Hello,
I'm working on connecting a optical digital audio receiver (DIR9001, for TOSLINK/COAX) to the multi-channel audio serial port (McASP) on the Beagle Bone Black. Whereas a PCM1690 DAC that I also connected…
Thanks for the swift response!
Having struggled with this for a day I actualy managed to progress to the next issue, so I might have been a bit quick on the trigger posting here.
I don't use a master clock (SCK on the PCM5142), but using the PLL with…
So, I'm at a point in my project where i would give you this feedback.
After more or less successful try's to make my own pcm to pwm converter in a fpga, i made a new pcb with a combination of a DIR9001, a TAS5548, two TAS5631 and a PIC uP for controlling…
