DS90LV049TMT

The Texas Instruments DS90LV049TMT is a dual CMOS flow-through differential line driver-receiver pair. It is designed for applications requiring low power dissipation, high noise immunity, and high data throughput, supporting data rates up to 400 Mbps using Low Voltage Differential Signaling (LVDS) technology.

The drivers in the DS90LV049TMT accept LVTTL/LVCMOS signals and translate them to LVDS signals. Conversely, the receivers accept LVDS signals and translate them to 3 V CMOS signals. The device features internal fail-safe biasing for the receiver inputs, ensuring a known high state for floating inputs. It operates over an industrial temperature range of -40°C to 85°C.

This transceiver is housed in a 16-pin TSSOP package, measuring 5 mm x 6.4 mm. The flow-through pinout simplifies PCB layout. Key electrical characteristics include a typical driver channel-to-channel skew of 50 ps and a receiver channel-to-channel skew of 50 ps. The device offers low power dissipation, consuming only 70 mW at 3.3 V static. Its LVDS outputs exhibit high impedance when powered down.

The DS90LV049TMT conforms to the TIA/EIA-644-A LVDS standard, making it suitable for various high-speed interface applications where signal integrity and low power are critical.
