  • PCM4204: Thermal Resistances/Max Junction Temp

    Part Number: PCM4204 The data sheet for the PCM4204 does not contain any thermal resistances. From a previous thread, I saw that the maximum junction temperature is 105°C. Is there any data available for junction to case and/or junction to ambient?…

  • PCM4204: Reading samples in slave mode

    Resolved
    Part Number: PCM4204 I am designing an acquisition system using the PCM4204. I will be running the 4204 in slave mode from a FPGA. The FPGA will input the SCKI clock and derive the BCK and LRCLK from that. I am going to use quad rate, left-justified PCM…

  • PCM4204 use exception

    Other Parts Discussed in Thread: PCM4204 When using PCM4204 EVM development board TDM mode, the board is configured as S/M=1, FMT2=0, FMT1=1, FMT2=1; /EXT=1, OSC1=0, OSC2=0; then FS2=0 , FS1 = 0, FS2 = 1 (Dual Rate), the acquisition frequency is set to…

  • RE: PCM4204: dynamic range of PCM4202 vs. PCM4222

    The better parts comparison is between the PCM4202 and PCM4204, where the latter is a four-channel version of the two-channel former. The PCM4222 is a different design, and notably it uses a +4.0 V analog rail rather than the +5.0 V rail of the 4202/4204…

  • RE: PCM4204: Question regarding unused channels

    Resolved
    Thanks! What is the ideal capacitance for AC coupling the unused inputs to ground? The PCM4204 has LRCK running at 48.8KHz and BCK running at 64 x LRCK. Thanks, Brian

    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 STOP BAND ATTENUATION CHARACTERISTICS SINGLE RATE FILTER PASSBAND RIPPLE CHARACTERISTICS…

  • RE: PCM4204: How to measure full-scale PDM(DSD) signal ?

    Hello! I have some question. Audio Precision PDM Module is used for DSD(PDM) signal generation. The PCM4204 was set DSD input to PCM output mode. If i put -6dBFS to PCM4204 DSD Input, how about PCM peak bit value of the PCM4204 ? If i put 0dBFS…

  • RE: PCM4204 TDM short frame format

    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 two…
