Texas Instruments DS90LV047ATMX/NOPB

Overview

DS90LV047ATMX/NOPB from Texas Instruments is a quad CMOS LVDS differential line driver operating at 3.3 V, delivering >400-Mbps data rates (200 MHz), 300-ps typical differential skew, and 1.7-ns max propagation delay. It translates TTL/CMOS inputs to ±350-mV LVDS outputs and supports TRI-STATE control via EN/EN* for ultra-low idle power (13 mW). Used in high-speed point-to-point interfaces such as multifunction printers and LVDS–LVCMOS translation.

For engineers reviewing the DS90LV047ATMX/NOPB datasheet, DS90LV047ATMX/NOPB pinout, DS90LV047ATMX/NOPB application, or DS90LV047ATMX/NOPB equivalent, key selection criteria include differential skew tolerance, flow-through PCB layout compatibility, LVDS standard compliance (TIA/EIA-644), and industrial temperature range (−40°C to +85°C) support.

Technical Context

The DS90LV047ATMX/NOPB implements a current-mode LVDS driver architecture with fixed 3.1-mA output loop current, requiring external 100-Ω termination to generate 310-mV typical differential voltage (VOD). Its AND-gated EN/EN* control enables simultaneous TRI-STATE of all four channels, achieving high-impedance outputs during power-down.

It operates strictly within 3.0–3.6 V supply range and demands matched differential trace routing due to its 0.4-ns max channel-to-channel skew and 1.2-ns max part-to-part skew. The device is not AC-coupled or unterminated-capable-resistive termination is mandatory for functional operation per its current-source design.

FAQ

What is the minimum recommended termination resistance for DS90LV047ATMX/NOPB?

The DS90LV047ATMX/NOPB requires a resistive termination between 90 Ω and 130 Ω, with 100 Ω being the nominal value specified in the datasheet. This resistor must be placed at the receiver end of the differential pair to convert the 3.1-mA current output into the required 310-mV typical differential voltage (VOD). Operation without termination is not functional-the device is a current-mode driver and cannot drive unterminated or AC-coupled lines.

Does DS90LV047ATMX/NOPB support hot-plug or live insertion?

No, DS90LV047ATMX/NOPB does not support hot-plug operation. Its absolute maximum ratings specify that input voltages must remain within −0.3 V to VCC + 0.3 V, and the device lacks built-in I/O protection for insertion under bias. Applying signals before VCC ramp-up-or removing VCC while inputs are driven-may exceed ESD or latch-up limits. System-level hot-swap capability requires external protection circuitry beyond DS90LV047ATMX/NOPB's native functionality.

Can DS90LV047ATMX/NOPB drive multiple receivers in a multidrop configuration?

DS90LV047ATMX/NOPB is designed for point-to-point use per TIA/EIA-644. While multidrop is electrically possible with careful impedance control, it is not characterized or guaranteed. Adding receivers increases capacitive loading and alters termination, degrading VOD, increasing skew, and raising jitter-especially beyond 2 receivers. TI recommends using a dedicated LVDS repeater or fanout buffer (e.g., DS90LV049) instead of relying on DS90LV047ATMX/NOPB for multidrop.

What is the purpose of the EN* pin on DS90LV047ATMX/NOPB, and how should it be handled if unused?

The EN* pin on DS90LV047ATMX/NOPB is an active-low enable that is ANDed with EN to control TRI-STATE. If unused, EN* must be tied to GND (not left floating) to ensure predictable enable behavior. Leaving EN* open may result in indeterminate output states due to noise coupling or internal leakage; TI explicitly states that "if both EN and EN* are open circuit, then the driver is disabled"-but this is not a robust default. For reliable operation, connect EN* to GND unless active inversion is required.

Is DS90LV047ATMX/NOPB compatible with 5-V LVDS receivers, and what ensures interoperability?

Yes, DS90LV047ATMX/NOPB is interoperable with 5-V LVDS receivers. Interoperability is ensured by strict adherence to the TIA/EIA-644 LVDS standard: its ±350-mV differential output swing and 1.2-V common-mode voltage (VOS) fall within the receiver input acceptance window (typically ±100 mV to ±400 mV differential, 0–2.4 V common-mode). No level-shifting circuitry is needed-this compatibility is verified in TI's application notes and cross-tested with industry-standard 5-V LVDS receivers like DS90LV048A.
