Part Number: PCM4204EVM Other Parts Discussed in Thread: PCM4204 Dear team,
I'm working on a prototype design based on the PCM4204,
Now I want the PCM4204 works in slave mode, thus, it requires a system clock input (24.576Mhz).
But RaspPi doesn't…
Part Number: PCM4204 My customer will only use channels 1 and 2 on a PCM4204 in their design. The Channel 3 and 4 are not used. Can we leave Vin3+, Vin3-, Vin4+, Vin4-, and SDOUT2 unconnected? How about Vref34+, Vref34-, Vcom34, AGND3?
Thanks,
Brian

We measure the signal level of PDM using PCM4204.
Using slave mode of PCM4204, we can measure properly when the input signal to the PCM4204 DSD input terminal is up to -6dBFS PDM.
However, when we put -3dBFS or 0dBFS which is greater…
Hello,
Do we have the numerical data for the following graphs on page 9 of the datasheet. A customer is requesting this.
OVERALL CHARACTERISTICS SINGLE RATE FILTER

Part Number: PCM4204 Other Parts Discussed in Thread: 66AK2G02 Hi team,
My customer wants to drive seven PCM4204s with a single 66AK2G02 and it's McASP peripheral. (specifically MCASP0_ACLKR, MCASP0_AFSR, MCASP0_AHCLKR generated internally in master mode…
Other Parts Discussed in Thread: PCM4204 , PCM4204EVM Hi,
In the data sheet of PCM4204, "Figure 4. PCM Data Formats: Tim Division Multiplexed(TDM)". I cannot understand the data allocation in the short frame mode.It says that the short mode support 4 channels…
Hello Mahendra,
I have the same questions with you. The data sheet says that the short frame mode "support 4 Channels, or two PCM4204 devices." . If there is only 1 chip(4 chs) with 128fs frame length (4 slots per frame), it does make sense. But…
Other Parts Discussed in Thread: PCM4201 , PCM4204 , PCM4104 Hi everyone,
I have designed a commercial board with an ADAU DSP, a pcm4201 and a pcm4204.
I am getting a backgroung noise in the ouput data line (TDM4 channels @48KHz) from the pcm4204 to the…
Other Parts Discussed in Thread: PGA2505 , PCM4204 , JFE150 , JFE2140 , JFE2140EVM , OPA1671 , OPA1678 , INA163 I'm designing a preamplifier for a GRAS 47AC microphone. It is a Pre-polarized 1/2" CCP mic with a frequency range from .09 to 20kHz. Does anyone have…
Hallo,
I'm also using the PCM4204. It is the master on a costum board and provides the clocks for a I2S connection to a MicroChip PIC24FJ128GB204 MCU and between the MCU and a PCM4104 DAC.
At the moment I'm trying to drive the MCU->DAC connection…
