LVDS signals. The receiver inputs accept low voltage

differential signals (LVDS, B-LVDS, M-LVDS, LV-

PECL and CML) and convert them to 3V LVCMOS

signals. The DS91D176 has a M-LVDS type 1

receiver input with no offset. The DS91C176 has an

M-LVDS type 2 receiver which enable failsafe

functionality.
