DESCRIPTION
The SN65MLVD2 and SN65MLVD3 are single-channel M-LVDS receivers. These devices are designed in full
compliance with the TIA/EIA-899 (M-LVDS) standard, which are optimized to operate at signaling rates up to
250 Mbps. Each receiver channel is controlled by a receive enable (RE). When RE = low, the corresponding
channel is enabled; when RE = high, the corresponding channel is disabled.
The M-LVDS standard defines two types of receivers, designated as Type-1 and Type-2. Type-1 receivers
(SN65MLVD2) have thresholds centered about zero with 25 mV of hysteresis to prevent output oscillations with
loss of input; Type-2 receivers (SN65MLVD3) implement a failsafe by using an offset threshold. Receiver
outputs are slew rate controlled to reduce EMI and crosstalk effects associated with large current surges.
The devices are characterized for operation from –40°C to 85°C.
