AD9643 have two  pin configurations， Parallel LVDS  and  Multiplexed (Even/Odd) LVDS; Which one do AD9643BCPZ-250 belong to?

从数据手册看，AD9643芯片有两种管脚定义方式， Parallel LVDS 和 Multiplexed (Even/Odd) LVDS 。请问AD9643BCPZ-250属于哪一种管脚定义方式？

想问下使用AD9643如何实现切换 0-1V  //-1~1V的两种信号，有成熟的的硬件方案？

Hi,

i am working on AD9643 ADC, i am not able to do the data output from this fro different input voltages as per the table11 given in datasheet.

i used a formula

DATAin decimal=(applied input volatge*2^14)/1.75

am getting

vin                 data            binary

-0.…

Dear  Sir/Madam,

I wonder how to use AD9634 to switch betwee 0-1V and -1V~1V, is there any solution for it.

Thanks.
