5505 USB stick

Other Parts Discussed in Thread: TMS320VC5505, TMS320C5505

We are designing a board based on the USB stick

And trying to get the part but it is out or stock evey where.

Would you clarify this.

We are over clocking it to 112Mhx. But the spec for TMS320VC5505 is 100Mhz.

Is it working because the part is TMS320VC5505ZCH12 and supports 120Mhz.

What is the device on the usb stickTMS320VC5505ZCH10?

Will it work at 112Mhz

    To be excat

    This is what I meant by over clocking, It is the PLL freq. we change on the USB stick

     

    #if (PLL_100M ==1)

        PLL_CNTL2 = 0x8000;

        PLL_CNTL4 = 0x0000;

        PLL_CNTL3 = 0x0806;

        PLL_CNTL1 = 0x837A;      //  PLL change 0x8346( 110 MHz)    0x8392(120 MHz)    0x82FA (100MHz);

       // PLL_CNTL1 = 0x8383 ;

    Microt,

    I don't know anything about availability, someone from the C5000 Product team will need to answer that.  I will point this question out to them.

    On overclocking, since we don't spec it the TMS320VC5505 for over 100 MHz, we can't guarantee the operation.  If you really need 112 MHz, then you should look at the TMS320C5505 which has replaced the original VC5505 device.  It contains a number of silicon errata fixes and is spec'd to run at 120 MHz.

    Regards.
