TAS5754 download time < 100mS (typ)? but I took 10 seconds to write the registers via I2C

Other Parts Discussed in Thread: TAS5754M

Hi Sir,

TAS5754M specs says ' download time < 100mS (typ).

however I take about 10 seconds to write its registers via I2C.

I check the waveform of I2C. It seems that  2 seconds is fastest speed if writing with full-time and 400kHz clock. 

my question: 

How to achieve '  download time < 100mS (typ)' ?

how to write all registers within 100ms?

best

    Hi, Alain,

    You may try changing the "Burst" field to 128 in the Direct I²C Read/Write tab of the TAS5754M GUI to shorten the length of the generated file and download time. Burst = 1 is the default value and equals to single byte I2C write.
