DS91M040

125 MHz Quad M-LVDS Transceiver

General Description

Features

■

The DS91M040 is a quad M-LVDS transceiver designed for

driving / receiving clock or data signals to / from up to four

multipoint networks.

DC - 125 MHz / 250 Mbps low jitter, low skew, low power

operation

Wide Input Common Mode Voltage Range allows up to

±2V of GND noise

■

M-LVDS (Multipoint LVDS) is a new family of bus interface

devices based on LVDS technology specifically designed for

multipoint and multidrop cable and backplane applications. It

differs from standard LVDS in providing increased drive cur-

rent to handle double terminations that are required in multi-

point applications. Controlled transition times minimize re-

flections that are common in multipoint configurations due to

unterminated stubs. M-LVDS devices also have a very large

input common mode voltage range for additional noise margin

in heavily loaded and noisy backplane environments.

Conforms to TIA/EIA-899 M-LVDS Standard

■

Pin selectable M-LVDS receiver type (1 or 2)

Controlled transition times (2.0 ns typ) minimize reflections

8 kV ESD on M-LVDS I/O pins protects adjoining

components

Flow-through pinout simplifies PCB layout

■

Small 5 mm x 5 mm LLP-32 space saving package

A single DS91M040 channel is a half-duplex transceiver that

accepts LVTTL/LVCMOS signals at the driver inputs and con-

verts them to differential M-LVDS signal levels. The receiver

inputs accept low voltage differential signals (LVDS, BLVDS,

M-LVDS, LVPECL and CML) and convert them to 3V LVC-

MOS signals. The DS91M040 supports both M-LVDS type 1

and type 2 receiver inputs.

Applications

Multidrop / Multipoint clock and data distribution

■

High-Speed, Low Power, Short-Reach alternative to TIA/

EIA-485/422

Clock distribution in AdvancedTCA (ATCA) and

MicroTCA (μTCA) backplanes
