bps (bits per second).

DESCRIPTION

The SN65MLVD040 provides four half-duplex transceivers for transmitting and receiving Multipoint-Low-Voltage

Differential Signals in full compliance with the TIA/EIA-899 (M-LVDS) standard, which are optimized to operate at

signaling rates up to 250 Mbps. The driver outputs have been designed to support multipoint buses presenting

loads as low as 30-Ω and incorporates controlled transition times to allow for stubs off of the backplane

transmission line.

The M-LVDS standard defines two types of receivers, designated as Type-1 and Type-2. Type-1 receivers have

thresholds centered about zero with 25 mV of hysteresis to prevent output oscillations with loss of input; Type-2

receivers implement a failsafe by using an offset threshold. The xFSEN pins is used to select the Type-1 and

Type-2 receiver for each of the channels. In addition, the driver rise and fall times are between 1 ns and 2 ns,

complying with the M-LVDS standard to provide operation at 250 Mbps while also accommodating stubs on the

bus. Receiver outputs are slew rate controlled to reduce EMI and crosstalk effects associated with large current

surges. The M-LVDS standard allows for 32 nodes on the bus providing a high-speed replacement for RS-485

where lower common-mode can be tolerated or when higher signaling rates are needed.
