TSC2007: I2C PU resister Value

Part Number: TSC2007

Tool/software:

Hi support team all.

I received an inquiry from my customer below.

[Q] 

The datasheet shows the representative circuit shown below,

but the SCL and SDA pull-up resistors are 1.2 kΩ, a low resistance value for an I2C pull-up resistor.

Do the pull-up resistors have to be 1.2 kΩ?

Or can I use another value (4.7 kΩ, for example)?

Best regards,

Higa
