Part Number: PCM1690 Other Parts Discussed in Thread: TPA3245 Hello all, i'm designing a PCB with the PCM1690 directly driving a TPA3245. Due to size and cost, i'm willing to sacrifice some 'dbs stopband attenuation by only using a passive reconstruction…
Part Number: PCM1690-Q1 Other Parts Discussed in Thread: PCM1690 Hello,
I'm FAE, I wonder if PCM1690 can support 16 channel time-division-multiplexed(TDM) by connect 2 pcs of devices, there is no related contents in our datasheet, but customer have…
Part Number: PCM1690-Q1 Other Parts Discussed in Thread: PCM1690 Hi team,
At initial power on below, what timing can I start to send I2C initialization command to PCM1690?
Is that after 3846 x SCLK clock cycle, or is that OK to send during internal reset…
Part Number: PCM1690 Other Parts Discussed in Thread: PCM1865 Hi team,
My customer just purchased 2 standalone EVM for the PCM1865 ADCs, but did not see standalone EVM for the PCM1690 DACs.
Best I can tell, there appears to be the K2G daughter card, which…
The outputs of the PCM1690 do not necessarily start at midscale if the device has experienced a clock error (stopping I2S input is always a clock error). I recommend that you start by providing only SCK, then apply LRCK and BCK with DIN=0. The only way…
Part Number: PCM1690 Other Parts Discussed in Thread: TPA3220 Dear Sir/Madam,
PCM1690 converts the I2S signal from an audio module to TPA3220.
Pls help review our SCH design if need to improve, many thanks! 6136.PCM1690.pdf
Part Number: PCM1690 Only the first 4 channels are working and we can’t get the channel 5/6/7/8 working. The board is used in Hardware mode. The configuration used is the I2S mode in single rate:
The input is the following:
The configuration…
Part Number: PCM1690PCM1690 only adjusts the power supply range of VCC1, VCC2, In 4.0V, 4.5V, 4.72V, 4.88V, 4.95V, 5.44V different voltage output, The output gain changes about 2dB. Is it normal? The following is the AP test report of the complete machi…
Part Number: PCM1690 Hi team,
I have a question about Vcc rising behavior.
Both Vcc will stay at 1.8V, then rise up to 5V as shown at the attached picture. After Vcc is stable at 5V, the reset operation in 7.3.5 of the datasheet has done.
Is there any…
Part Number: PCM1690-Q1 Other Parts Discussed in Thread: PCM1690 , Hi Team,
We would like to know the difference between Thermal resistance of PCM1690-Q1 and PCM1690(Non Q1).
I understand that Θ JA of PCM1690-Q1 is 23 ℃ /W but I can’t find other parameters…
