Part Number: TPIC8101
Other Parts Discussed in Thread: PLL1707-Q1

Hi Experts,

We'd like to ask assistance looking for TI solution for a lower Center frequency than 1.22kHz. Can you recommend an alternative?

Is there a frequency multiplier I can apply to the input signal to get it into range of the TPIC8101?

Regards,
Colin

Hi ArTzy,

Our experts on this topic are currently out of office for the holidays. They should be able to respond sometime after they are back on January 5th.

Hi Colin,

After doing some research into this, using a PLL frequency multiplier, you should be able to get the input signal frequency into a range where the center frequency is configurable.

I hope I was able to answer your question. If you need any further assistance, please let me know.

Best regards,
Chase Girard

Thanks.

Can you recommend a TI PLL to use in this low frequency application?

PLL1707-Q1?

Hi Mason,

No I do not have a specific recommendation for a specific PLL as this is not an implementation we have explored with this device.

You may want to try to ask this question on the Clocks & Timers forum where these devices such as the PLL1707-Q1 are supported.

Best regards,
