Hi,

The PCB copper size refers to the area of copper on the board. Table 7 displays how that amount of copper area affects theta-JA measurement where the larger the area, lower the theta-JA value and the better it dissipates heat.

Hi,

You can use ADP7156 which is a 1.2A, ultralow noise, high PSRR, RF linear regulator that offers fixed output voltage of 1.8V and 3.3V for easy pairing with the AD9914.

Best regards,

Hi Sai,

With regards to the DC power regulator, I assume you are referring to ADP7156/7.

Yes, this is suitable for the AD9914.

Best regards,

If the LTC6953 is powered up with all outputs on it will exceed the LT3045 current.  There are few work arounds, I listed a few options in no particular order.

1) Set the LTC6953 !SD pin low on power up. Program the LTC6953 SPI to your desired configuration…
