No, the AD9856 does not offer any pulse-shaping functionality. Please note that if you do some pulse shaping to the data prior to inputting it into the AD9856, there are implications on the AD9856 functionality - be sure to read the section on the half…
ad9856
不好意思写的比较长，还有图，是想让人看得明白一些。
希望用AD9856做一个正交调制，I、Q两支路为码速率4.2966MHz的数字信息，经过AD9856正交调制之后输出为20MHz的中频信号，系统框图如下图：
上图中的脉冲成型滤波模块以4倍采样对I、Q两路信息进行脉冲成型滤波，输出为17.1864MHz（4.2966MHz×4）的有符号数（输出字长15比特，取高12位（第3——15位）输入AD9856，最高位为符号位，满足AD9856二进制补码的输入要求）。
写AD9856（红色框）将I、Q两支路脉冲成型后的数据按照I1…
Hi Ivan,
I will have to get back to you on this as the AD9856 evaluation board is already obsolete.
Thanks.
I wanted to simulate, Evaluation board schematic as per provided in the AD9856 datasheet.
I am using ADIsimPE but in that, I am not getting AD9856 part details to place it. Also, I was unable to get AD8320 for the same.
I made a hardware interface of…
Hi, Dr. Babankumar.
For your qeustions:
1. Other QDUCs (quadrature digital upconverters) that we have are AD9856 and AD9857.
2. No, it needs a Parallel port connection.
3. I'll get back to you on this.
4. As of today, what we have is AD9914 which…
接上
Yes we do. We have an extensive portfolio of dual DACs with maximum speed from 125Msps to 1.25Gsps with resolution from 8 to 16 bits.We also have a quad DAC, AD9148, with the plan to develop further this line of products. Attached is a file describing…
