The SN65LVDM1676 and SN65LVDM1677
(integrated termination) are sixteen differential
line drivers and receivers configured as trans-
ceivers that use low-voltage differential signaling
(LVDS) to achieve signaling rates in excess of
600 Mbps. These products are similar to
TIA/EIA-644 standard compliant devices

(SN65LVDS) counterparts except that the output
current of the drivers are doubled. This modification provides a minimum differential output voltage magnitude
of 247 mV into a 50-Ω load and allows double-terminated lines and half-duplex operation. The receivers detect
a voltage difference of 100 mV with up to 1 V of ground potential difference between a transmitter and receiver.
