TMP75: Max value of the SCL operating frequency in FAST MODE

KAEDE KUDO

Part Number: TMP75

Hello,

My customer has a question.

[Q]

What is the maximum reference value for the SCL operating frequency in FAST MODE?
They understand that 400kHz listed in the D/S is a guaranteed value, but they say that they want the SCL operating frequency data as a reference value.
Is there any data that can be provided?

Best Regards,

Kaede Kudo

Dear Kudo -

The I2C spec has the timings for this - see Table 10 on page 48 - does this fufill the request?

Hi Kaede,

The SCL is controlled by the I2C Host. TMP75 is not capable of driving the SCL line. Our device doesn't have a reference frequency; it must operate according to the clocking provided by the host.

thanks,

Ren
