Can I drive the AD8156 from an LVDS or LVCMOS sources (eg, VCXO output)?
The AD8156 can interface to LVDS and LVCMOS sources. Both sources should be
AC-coupled to the AD8156. If DC-coupling is required please contact ADI
technical support as some non-ideal adjustments would need to be made to the
AD8156 in-order to ensure input common-mode compliance.
