Are ADN4696E compatible with ADN4662?

Question

Hello, 
 are the ADN4696E/ADN4697E logic level compatibles with ADN4661/ADN4662? 
 Can I directly connect these 2 devices? 
 Thanks in advance 
 Maurizio.

Hello Maurizio, Thank you for the explanation. If I understand correctly, the board in design may be SPI master or slave (Potentially ADN4696E for the interface) that will connect to one other board (either a master or a slave, with ADN4661/ADN4662). Going by the datasheets for these devices, this should work, but contention should be avoided where there is an ADN4661 at the other end of a channel. For example when the new board is connected, have all the ADN4696E devices in receive only mode (DE and /RE low) to begin with. If I understand correctly, there would be the following two cases for the new board once it is connected: New board is Master: SPI signal (as LVDS) New Board (as master) Devices Direction Old Slave Board Devices /CS ADN4696E (DE high, /RE high) ---> ADN4662 CLK ADN4696E (DE high, /RE high) ---> ADN4662 MOSI ADN4696E (DE high, /RE high) ---> ADN4662 MISO ADN4696E (DE low, /RE low) <--- ADN4661 New board is Slave: SPI signal (as LVDS) New Board (as slave) Devices Direction Old Master Board Devices /CS ADN4696E (DE low, /RE low) <--- ADN4661 CLK ADN4696E (DE low, /RE low) <--- ADN4661 MOSI ADN4696E (DE low, /RE low) <--- ADN4661 MISO ADN4696E (DE high, /RE high) ---> ADN4662 Regards, Conal
