Part Number: LMX2594
I want to know the default output status of the LMX2594, when it is powered up first.
I'm using 100MHz TCXO with 7833 MHz loop filter components.
Thanks in advance.

Thanks for the reply.
One more query, I need to test the LMX2594 board, which is designed by me, is there any precaution we need to take for testing by default? If yes please give me the details.

Thanks for the reply and valuable info.
Hello Fung,As you said I'm trying to program my LM2594 using USB2ANY, I'm able to send the data , but how do I confirm that, am I writing or not? TICS Pro sending data even if I don't connect my LMX2594 board to USB2ANY. I'm keeping both outputs off. I can't turn it on right now because of my hardware constraints. Please help me through this.
To test that the LMX2594 is actually understanding commands from USB2ANY, try some of these tricks:
1. Use the powerdown bit to power the device up and down. You should see the current change. If you can't measure current, look at the DC bias level at the OSCin pin. It should be about 1.5V when powered up, 0V when powered down.
2. TICSPro allows you to read back registers. To do so, set LD_MUXOUT_SEL to "ReadBack" and go to the "registers" tab and type in a register to readback.
3. If programming our EVM, the green light should come out when the PLL is locked.
