LMK03328: LMK03328 EEprom programming

Part Number: LMK03328
Other Parts Discussed in Thread: , USB2ANY

Hello.

Please find attached the LMK03328 TICS configuration file.LMK03328_DSRT_Clocks.zip

I don’t receive any output clock after eeprom programming by i2c.

The gpio pins are confirured as:

refsel, gpio0=0

gpio1=1

gpio2,3=0

gpio4=1

I have an input clock of 108M and I need the following outputs:

 

Out0: 100M LVDS

Out1: 100M LVDS

Out2: 100M LVCMOS

Out3: 100M HCSL

Out4: 25M LVCMOS

Out5: 25M LVCMOS

Out6: 135M LVDS

Out7: 108M LVCMOS

What can be the problem?

Thank you

    Try setting GPIO0 to 1 to deassert output SYNC.  Or, if SYNC isn't needed,  clear PLL SYNC bits to disable output sync.

    Dear Alan,

    Customer has the device on their board and he wants to program the device on the production floor.

    We've noticed neither the TICS pro or the clock architect describes the exact registers it programs on the log window.

    Can you advise any quick way of programming the device on the production floor.

    Best regards,

    Nir.

    Nir,

    Sorry for the delay in response.  Is this question still open? 

    If no, could they use a LMK03328EVM and blue-wire the SDA/SCL/GND lines from the EVM to the target device on the customer's board and program it using the TICS Pro?  They can disconnect the LMK03328 on the EVM from the I2C bus, so that the USB2ANY + GUI interface can communicate with the target device without conflicting with another device.  Once they establish I2C communication with the target device, the GUI can be used to program the device in the same way as on the EVM.

    Regards,
    Alan
