SLLS430D – NOVEMBER 2000 – REVISED JUNE 2007

HIGH-SPEED DIFFERENTIAL LINE TRANSCEIVERS

• Sixteen Low-Voltage Differential Transceivers.

Designed for Signaling Rates up to 200 Mbps

per Receiver or 650 Mbps per Transmitter.

• Simplex (Point-to-Point) or Half-Duplex

(Multipoint) Interface

• Typical Differential Output Voltage of 340 mV

Into a 50-

Ω Load

• Integrated 110-Ω Line Termination on

'LVDM1677 Product

• Propagation Delay Time:

–

Receiver: 3 ns Typ

• Driver is High Impedance When Disabled or

Glitch-Free Performance and Hot-Plugging

Events

• Packaged in Thin Shrink Small-Outline

Package With 20 mil Terminal Pitch

The

SN65LVDM1676

and

SN65LVDM1677

(integrated termination) are sixteen differential line

transmitters

or

receivers

(tranceivers)

that

use

low-voltage differential signaling (LVDS) to achieve

signaling rates up to 200 Mbps per transceiver

configured as a receiver and up to 650 Mbps per

transceiver

configured

as

a

transmitter.

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.
