TMS320F28234: TMS320F28234

Kevin Finkbiner

Part Number: TMS320F28234

Does the TMS320F28234 have the capability of clocking from an internal source. I am currently using an external 30 Mhz ceramic resonator, CTS PN: 405C35F30M00000, and it works great. I am running the TMS320F28234 at 150 MHZ. I know the Piccolo processors can be clocked entirely from internal sources. Is there a way to eliminate the external resonator and run at 150 MHZ?

Hi Kevin,

Simply go through 5.2.1 PLL-Based Clock Module in User Guide. Let me also paste the extract:

Kevin,

The TMS320F2823x/2833x series does NOT have an on-chip clock source. You need to use an external crystal, resonator, or clock.

David,o
Thanks for verifying the clock source for me. There is a lot of data available for lots of devices and I just wanted to verify I understand correctly.

Thank you,
Kevin
