Part Number: PCM1840 Other Parts Discussed in Thread: PCM1690 ,
Hello together,
we use an PCM1840 as ADC while we are using the PCM1690 as DAC. For the PCM1840, we have configured it in Slave Mode (4-channel output with time division multiplexing (TDM…
Part Number: PCM1840 Other Parts Discussed in Thread: PCM1804 , , PCM1821 , PCM5102A , TLV320DAC3203 Hello,
Our customer validate PCM1804 function at slave mode 32BCK I2S input from BT module with internal PLL mode which reference to BCK input.
In this BT…
Part Number: PCM1840 Hello,
we designed in the PCM1840 on a board. There are 5 ADCs, 1 x as master and 4 x as slave. After a few adjustments, these work well and the processing in the FPGA also works very well.
Our question now is whether the following…

Hello team.
I checked that PCM1840 has a Digital High-Pass Filter and its cuttoff frequency at 96 KHz sample rate is 24 Hz.
Is it possible disable/turn off/by pass that HPF ???
Thank you in advanced.
Part Number: PCM1840 Hi Team,
Based on the format pins description in section 7.3.2, it only supports outputting TDM 4 with 32-bit slot width.
But table 3 of section 7.3.3 shows that it supports BCLK / FSYNC = 256. It is a conflict with what mentioned…
Part Number: PCM1840 Hi,
Could you please share the dynamic performance(SNR, DR and THD+N) at 96kHz with me if possible? The PCM1840 data sheet is mentioned only at 48kHz.
Best regards, Kato
Part Number: PCM1840 Hi Team,
do you have the die code information for this MPN :
PCM1840IRTWR
also i have a question on why the column (L)TO : xxxx is with 0000, it is normally filled with numbers. see below image.
Part Number: PCM1840 Hi,
Sorry for the basic question. The customer inquired about the ADC clock frequency before decimation. How is the "Delta-Sigma Modulator" clock defined?
Looking at the data sheet P15, there is a description of "system clock…
Part Number: PCM1840 Hi Team,
As the Figure 1 PCM1840 DATASHEET typical circuit. The IC input front side has 1uF capacitor isolation. If there is no capacitor, is it possible to have a bias voltage of 2.5V? Please refer to Figure 2 Connection Method
