Can i drive the LMX2582 with 1.8V SPI and Vcc=3.3V? In my current design, i have connected Vcc to 3.3V but my SPI lines are 1.8V compatible.

Hello Jagannatha,
Yes, this is possible. Please refer to the high/low input voltage rows under the "Digital Interface" section of the "6.5 Electrical Characteristics" . Any voltage above 1.4 V will be registered as high and any voltage under 0.4 V will be registered as low.
Thanks,
Vibhu
