TCA9617A: Max Freq

Part Number: TCA9617A

Hi Team,

Customer wants to check operation condition if ok.

VCCA = 1.8V, VCCB = 3.3V, Speed = 1MHz, application is I2C redrive, distance up to 2m.

Also, will this device be able to operate at 1MHz throughout entire temp range?

Thanks!

Andrew

    Hi Andrew,

    Yes, this device redrives the I2C signal to provide true-buffering to the I2C bus. The propagation delays and transition times for this device can support 1MHz operation throughout the specified temperature range. Keep in mind that the rise-time of the signal is primarily determined by pull-up strength and line capacitance (trance/cable distance) and can have an impact on achievable data rate. 

    Let me know if you have any more questions.

    Regards,
    Eric Schott
