LTC2386 not producing any data

Category: Hardware
Product Number: LTC2386-18

My LTC2386-18 isn't producing any data on the DA output. DCO shows the reflected SCLK, and I'm in single lane mode. It's the same whether TestPat is high or low.

I'm driving CONV+ using LVTTL levels and CONV- is pulled low by my FPGA. Does CONV- have to be pulled hard low?

    Based on its datasheet, CNV- should be tied to ground if your CNV+ is driven by 2.5V CMOS signal.
