LMK03328: The min I2C speed of LMK03328

Nick Dai

Part Number: LMK03328

Hi Team,

My customer designed LMK03328RHSR with 99.502kHz I2C interface and 2.5uS SDA hold time,but the min clock rate of I2C is 100kHz and the max SDA hold time of LMK03328 is 100kHz and 0.9uS.

Could you help check could LMK03328 wotj on customer board and is there any risk?

Best Regards,

Nick Dai

Hi Nick,

I spoke to the design team and they do not have any concerns with the customer's operating condition.

Hi,

Can you please confirm what the minimum I2C frequency is for this device? I wish to run at a lower frequency than specified. Obviously I will still need to comply with rise and fall requirements.

Are there any non-standard 'time-outs' I need to be concerned about if I do?

Kind Regards,
Chris Burton

The IC designer says it has a bus timeout, so keep bus rate at 10kHz or higher.
