• How to set up LTC2174 properly?


    I'm using LTC2174 on a FMC ADC board card. I want to program the mode control registers on LTC2174 which is SPI interface. But I can't get right readback data of registers(all bits are "1"). I'm not sure whether the ADC was set…

  • How to produce Frame Clock(FR) of the ADC?


    I'm using a FMC board card with ADC - LTC2174. After power on,I can detect DCO signal of the ADC with Oscilloscope. However I can't detect FR signal.

    1. I think that FR signal will be automatic generated after power on (just like DCO signal…

    The Vcm on My Demo board DC1751 doesn't have output,is it wrong?And what the output type of FR and DCO ?LVDS?

  • ADF4356 for ADMV1013/14


    I am using ADF4356 for ADMV1013/14. I just found out the max RFOUT power for ADF4356 is -2 dbm at 6.8GHz. ADV1013/4 requires LO input is within -6 to 6 dbm. What will happen if LO power is less than -6dbm? Let's say LO input at ADMV1013 only sees…

  • RE: LTC2153-14 CLKOUT

    The CLKOUT will follow the ENC signal with a small delay.  If ENC is high then CLKOUT will be high shortly after that. 

    The default it 0 degree phase shift

    There is no reason to dynamically change the phase of the output clock.  It is something you set…

  • LTC2314-14 not working

    LTC2314-14 is not working. Only zeros coming on SPI. I am using STM32L431RBT6 as SPI master at 8MHz.

    I used the following code:


    HAL_SPI_Receive(&hspi1,(uint8_t *)&buf…

  • LTC2258-14 No output or CLKOUT

    We are trying to use the ltc2258-14 with the serial programming mode, Double data rate CMOS.  We can not get any output on the clkout line or any of the data lines.  We have also been unable to read any of the mode registers.

    Any thoughts as to why we wouldn…
