DS90C2501SLB 162MHz LVDS LDI Transmitter | Texas Instruments
MPN: DS90C2501SLB ✓ ActiveDS90C2501SLB Overview
An LVDS display interface, also called LDI, is a high-speed differential signaling method for transferring pixel data between a graphics source and a display panel. By transmitting data differentially, it reduces sensitivity to electromagnetic interference while delivering the bandwidth required for high-resolution panels. Within the broader semiconductor hierarchy, the DS90C2501SLB is an interface IC and, more specifically, an LVDS transmitter with integrated scaling.
The principal features of the DS90C2501SLB include a maximum stated operating frequency of 162 MHz, a 3 V to 3.6 V supply range, a 1/0 driver-to-receiver configuration, and support for LVDS signaling. Its integrated scaler consolidates scaling and transmission into one device, which can reduce the number of separate processing and interface components required in a display link. The package also includes thermal-pad structures in the CSPQFN configuration.
Technically, the device is designed around the industry-standard LVDS interface and is intended to support the bandwidth of high-resolution display panels while keeping clock rates low enough to limit EMI and shielding requirements. The built-in scaler accepts a single-pixel stream and conditions it for LVDS panel transmission, combining display-format conversion with low-voltage differential output. This integration is useful where component count, board area, and signal-path complexity are important constraints.
Typical uses include small-panel and embedded LCD controllers, industrial human-machine interfaces, point-of-sale terminals, automotive-style navigation displays, and other systems that send pixel data from a host controller to an LVDS display. It is particularly suitable when the source provides a single-pixel input and the panel requires a scaled LVDS output rather than a separate scaler followed by a discrete transmitter.
The main design consideration is that this is a display-interface device with one transmit direction and no LVDS receiver. It cannot replace a bidirectional LVDS transceiver, and firmware must configure the host link, panel timing, and scaling ratio correctly. Use the pin-description table and application circuit in the manufacturer datasheet when assigning the 128 terminals and the exposed thermal pads.
This page brings together the device specifications, package information, application fit, design guidance, and verified sourcing details. It also distinguishes the DS90C2501SLB from generic LVDS drivers and transceivers so design teams can determine whether its integrated scaler, single-pixel input, and 128-terminal footprint match the intended display architecture.

Typical Applications
DS90C2501SLB is suitable for 6 applications: Industrial Human-Machine Interface Displays, Point-of-Sale Terminal Displays, Embedded LCD Controller Boards, Automotive Navigation Display Interfaces, Medical Panel and Diagnostic Displays, Low-EMI High-Resolution Panel Links.
Industrial Human-Machine Interface Displays
The DS90C2501SLB fits an industrial HMI panel that accepts a single-pixel stream and expects an LVDS display output. Its integrated scaler combines pixel-format conditioning with LVDS transmission, which can reduce the number of separate interface stages in a compact controller. The 162 MHz maximum stated frequency supports the bandwidth required by high-resolution panels, while the 3 V to 3.6 V operating range aligns with a conventional 3.3 V system. Panel timing, scaling ratios, and temperature requirements must be verified for each display before schematic release.
Point-of-Sale Terminal Displays
A point-of-sale terminal often needs a compact display subsystem that converts an embedded graphics output into a panel-compatible LVDS link. The DS90C2501SLB accepts a single-pixel input and scales the image for transmission at resolutions up to SXGA+, making it useful where a separate video scaler would add cost and board area. The transmitter-only configuration suits a one-way host-to-panel architecture. Because it has no receiver, the display bus cannot be used for bidirectional control traffic, so touch or configuration data must travel through a separate interface.
Embedded LCD Controller Boards
The DS90C2501SLB is appropriate for an embedded controller that must drive an LVDS LCD from a host processor or programmable display controller. Combining scaling and LVDS transmission can simplify the video path, while the 128-terminal 10 mm by 10 mm package keeps the solution compatible with high-density surface-mount assembly. Designers should allocate routing space for fine-pitch differential pairs and thermal vias under the CSPQFN thermal pads. The commercial temperature grade also requires confirmation against the enclosure temperature and the target display's operating environment.
Automotive Navigation Display Interfaces
The DS90C2501SLB can serve as the panel-side LVDS transmitter in a navigation or infotainment display design that begins with a single-pixel video stream. Its integrated scaler supports resolution up to SXGA+, providing a path from host-generated imagery to an LVDS panel without a separate scaling stage. The transmitter architecture directs data toward the display and cannot replace a bidirectional automotive LVDS link for control or status feedback. Automotive deployments should confirm the exact temperature grade, electromagnetic requirements, and AEC-Q100 qualification status for the ordered device before production use.
Medical Panel and Diagnostic Displays
The DS90C2501SLB may be used in a medical display module where a host controller feeds a single-pixel stream to an LVDS panel. The integrated scaling and transmission functions help maintain a compact signal chain, and the one-driver architecture is appropriate for a unidirectional panel link. Display timing and refresh characteristics must be validated against the specific panel module because LVDS timing margins determine whether image artifacts or synchronization errors appear. The commercial temperature grade and lack of stated medical-device qualification must be assessed against the system enclosure and regulatory design requirements.
Low-EMI High-Resolution Panel Links
The DS90C2501SLB suits LVDS panel links where reduced clock rate and lower electromagnetic emissions are priorities. The manufacturer describes the LVDS architecture as providing the bandwidth needed for high-resolution panels while keeping clock rates low enough to limit EMI and shielding requirements. The 162 MHz maximum stated frequency defines the transmitter's headline operating capability, while the 3 V to 3.6 V supply supports conventional panel-controller designs. Final emission performance depends on connector selection, cable routing, shielding, and compliant PCB implementation rather than the IC alone.

Design Notes
Route each LVDS differential pair as a tightly coupled, length-matched pair over a continuous reference plane. Keep the pair geometry consistent across the transmitter, connector or flex interface, and panel entry point, and avoid test pads or unprotected stubs on the nets. Follow the reference-plane and via guidance in the manufacturer datasheet because discontinuities at the connector or panel transition can degrade the differential signal and contribute to emissions.
Treat the CSPQFN thermal pads as part of the electrical and thermal design rather than optional copper. Follow the manufacturer land pattern for thermal-via placement and verify the exposed-pad connection and any required shell or pad connections in the pin table. Because no thermal resistance or dissipation figure is stated for this package, junction-temperature analysis should use the actual supply voltage, output-load current, board copper area, and ambient conditions of the finished assembly.
Do not treat the DS90C2501SLB as a general-purpose bidirectional LVDS link. It contains one driver, no receiver, and an integrated display scaler, so host-to-panel data flows in one direction. Confirm the supported input and output timings, scaling ratios, and panel resolution before committing the design, and do not substitute a generic LVDS transceiver without a complete pin and functional review.
