I2C failure - SCL glitches

$

Hello,

In our designs we are using OMAP-L138 and seeing I2C failures. I2C0 is connected to EEPROM, Temperature sensor and to a I2C mux.

Through I2C mux OMAP-L138 talks to a third-party power supply.The I2C device address on the third-party power supply is 0x10.

Below is the capture of one such failure - part of write transaction.

The actual transaction should look like below.

We are seeing glitches on SDA also. but mostly when the SCL is low.

Regards,

Srinivas.
