description

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.
