TMS320F28069: oscillator info

Tjark Smatt
Prodigy 20 points
Part Number: TMS320F28069

TMS320F28069-Q

Hello, I need additional info on TMS320F28069-Q1 please:

For evaluation of TMS320F28069-Q1 + external clock (Pin 59+60 in 100Pin package), I need further info on below points, please:

-Load capacitor CL internally (yes/no)

-Typ value int load capacitor

-Oscillator gain/loop controlled (AGC, HW, SW)?

-Detailed description of gain/loop control (strategy, timing etc.)

Thanks in advance and BR,

Tjark

    Hi Tjark,

    The oscillator doesn't have an internal CL as far as i'm aware. CL is the effective load capacitance seen by the oscillator. We have a ESR specification in the datasheet which correlates with the gain of the oscillator circuit. The oscillator gain loop is an analog loop implemented in hardware.

    Can you provide more information on what parameters you are trying to measure?
