Part Number: PCM1789

Hi Team,

Would you advise about my customer inquiry that

1, There is below description on page 3 in PCM1789-Q1 datasheet but no description in PCM1789 datasheet. Is this common for both devices?

    　(1) BCK and LRCK (Schmitt trigger input with 50-kΩ typical internal pull-down resistor).

　　(2) DIN (Schmitt trigger input).

　　(3) SCKI, ADR5/ADR1/RSV, MC/SCL/FMT, MD/SDA/DEMP, and AMUTEI (Schmitt trigger input, 5-V tolerant).

　　(4) RST and MS/ADR0/RSV (Schmitt trigger input with 50-kΩ typical internal pull-down resistor, 5-V tolerant).

　　(5) ZERO1 and ZERO2.

　　(6) AMUTEO and SDA (I2C mode, open-drain low output).

2. My customer use PCM1789 with hardware control mode. please advise below connection no problem?

    ① Are 18pin ZERO2/AMUTEO and 19pin ZERO1 open no problem?

    ② Can the customer connect 23pin(MS/ADR0/RSV) and 24pin(ADR5/ADR1/RSV) to GND directly?

Thanks

Best regards,
