 The serial interface is digitally isolated. High speed complementary metal-oxide semiconductor (CMOS) technology, combined with monolithic transformer technology, results in the on-chip isolation providing outstanding performance characteristics, superior to alternatives such as optocoupler devices. The [[adi>ADuM7701]] device is available in both a 16-lead and an 8-lead wide-body SOIC and has an operating temperature range of −40°C to +125°C. The serial interface is digitally isolated.

-The provided HDL reference design support's both the ADuM77701 and AD7405 devices. One of the main difference between thees two devices is the type of the digital data lines. In case of ADuM7701 it is a single ended lines, and in case of the AD7405 is differential. +The provided HDL reference design support's both the ADuM7701 and AD7405 devices.

 User can configure the corresponding interface type, by setting the **adc_port_type** Tcl variable in the system_project.tcl file. Note that this variable should be set before generating any bit file.  User can configure the corresponding interface type, by setting the **adc_port_type** Tcl variable in the system_project.tcl file.

-The output of the device is a continuous digital bit stream, to reconstruct the original input signal information, this output bit stream needs to be digitally filtered and decimated. A simple {{https://github.com/analogdevicesinc/hdl/blob/adum7701/library/common/util_dec256sinc24b.v|sinc filter}} is recommended to reconstruct the original input signal information received from the ADuM7701. The following equation describes the transfer function of the sinc filter: +The output of the device is a continuous digital bit stream, to reconstruct the original input signal information, this output bit stream needs to be digitally filtered and decimated.
