This device family has robust • Compatible with the M-LVDS Standard TIA/ 3.3-V drivers and receivers in the standard SOIC and EIA-899 for Multipoint Data Interchange QFN footprint for demanding industrial applications. • Low-Voltage Differential 30-Ω to 55-Ω Line Drivers The bus pins are robust to ESD events, with high and Receivers for Signaling Rates(1) Up to 100 levels of protection to human-body model and IEC Mbps, Clock Frequencies up to 50 MHz contact discharge specifications. – Type-2 Receiver Provides an Offset Threshold The SN65MLVD204B combine a differential driver to Detect Open-Circuit and Idle-Bus Conditions and a differential receiver (transceiver), which operate • Bus I/O Protection from a single 3.3-V supply. The transceivers are – >±8-kV HBM optimized to operate at signaling rates up to 100 – >±8-kV IEC 61000-4-2 Contact Discharge Mbps. • Controlled Driver Output Voltage Transition Times The SN65MLVD204B has enhancements over similar for Improved Signal Quality devices. Improved features include a controlled slew • -1-V to 3.4-V Common-Mode Voltage Range rate on the driver output to help minimize reflections Allows Data Transfer With 2 V of Ground Noise from unterminated stubs, resulting in better signal • Bus Pins High Impedance When Disabled or VCC ≤ integrity. The same footprint definition was 1.5 V maintained, allowing for an easy drop-in replacement • 200-Mbps Device Available (SN65MLVD206B) 1 for a system performance upgrade. The devices are • Improved Alternatives to SN65MLVD204A characterized for operation from –40°C to 85°C. 2 Applications The SN65MLVD204B M-LVDS transceivers are part of TI’s extensive M-LVDS portfolio. • Low-Power, High-Speed, and Short-Reach (1) Alternative to TIA/EIA-485 Device Information • Backplane or Cabled Multipoint Data and Clock PART NUMBER PACKAGE BODY SIZE (NOM) Transmission SN65MLVD204B SOIC (8) 4.90 mm × 3.91 mm • Cellular Base Stations SN65MLVD204B WQFN (16) 4.0 mm x 4.0 mm INFORMATION ADVANCE • Central Office Switches (1) For all available packages, see the orderable addendum at • Network Switches and Routers the end of the datasheet. 3 Description The SN65MLVD204B device is a multipoint-low- voltage differential (M-LVDS) line drivers and SPACER D DE RE A R B Simplified Schematic, SN65MLVD204B 1 The signaling rate of a line is the number of voltage transitions that are made per second expressed in the bps of the unit (bits per second).
