DS90CF562MTD - 18-Bit LVDS FPD Link | Texas Instruments
料号： DS90CF562MTD ✓ 量产中DS90CF562MTD 概述
An LVDS flat-panel display link is an interface within the broader display-interface and data-conversion hierarchy. LVDS means low-voltage differential signaling: a small-amplitude differential signal transfers information over a balanced pair, providing useful noise immunity and allowing display data to travel between circuit boards or across a cable. The DS90CF562MTD is therefore positioned as a display-interface IC rather than a general-purpose logic device, communications transceiver, or graphics processor.
Key features include 18-bit color flat-panel display support, 21-bit CMOS or TTL input data, three LVDS data streams in the associated interface family, and a 48-pin TSSOP package. The differential signaling architecture is intended for display links where data integrity, common-mode noise rejection, and deterministic clocking are important. Commercial temperature-grade positioning and surface-mount construction suit compact industrial, instrumentation, and embedded display systems.
The DS90CF561/DS90CF562 interface family uses a phase-locked transmit-clock arrangement, allowing the clock to be carried in parallel with the serialized LVDS data. This architecture separates clock transport from the three low-voltage data lanes and helps the receiving display interface reconstruct the required pixel stream. Implementation still requires careful control of data timing, differential impedance, connector or cable geometry, and grounding.
Typical applications include industrial flat-panel displays, test and measurement equipment with integrated screens, medical monitoring displays, point-of-sale terminals, automotive information displays, and embedded human-machine interfaces. In these systems, the interface connects a graphics engine or display controller to an LVDS-capable panel while using low-amplitude differential signaling to support longer interconnects than a conventional single-ended display bus.
When laying out a board, treat the differential pairs as controlled-impedance nets and keep the transmitter and receiver interfaces away from noisy power stages. Use the manufacturer datasheet for the exact pin assignments, supply requirements, timing limits, and reference circuit before assigning tracks or selecting bypass capacitors. The 48-pin TSSOP footprint also requires adequate assembly-line spacing and a pin-one orientation that follows the package drawing.
This page combines the device's documented interface function, package information, sourcing data, application context, and design guidance. It also distinguishes the exact DS90CF562MTD ordering code from related family members and explains where engineers should verify pin compatibility before treating any proposed substitute as a drop-in replacement.

典型应用
DS90CF562MTD 适用于 6 应用s: Industrial Flat-Panel Display Interface, Test and Measurement Equipment Displays, Medical Monitoring Displays, Point-of-Sale Terminal Displays, Embedded Human-Machine Interfaces, Automotive Information Displays.
Industrial Flat-Panel Display Interface
The DS90CF562MTD fits the receiving side of an industrial display connection that uses the DS90CF562 LVDS interface. The associated family accepts 21 bits of CMOS or TTL display data and transports information as three LVDS data streams with a phase-locked clock path. Differential signaling reduces susceptibility to common-mode noise compared with a single-ended display connection, which is valuable near industrial motors, switching supplies, and long interconnects. The 48-pin TSSOP package also supports compact controller boards. Before layout release, confirm the panel’s supported data grouping, clock polarity, connector mapping, and timing against the National Semiconductor datasheet.
推荐
Test and Measurement Equipment Displays
DS90CF562MTD can provide the LVDS receiving interface for an instrument that combines a local display with measurement circuitry. The three-data-stream LVDS arrangement and parallel phase-locked clock transport are suited to a structured graphics interface between a display controller and a panel. This can simplify cable routing compared with carrying many single-ended pixel signals, while differential signaling improves noise immunity in dense instruments that include switching power converters. Use the manufacturer datasheet to establish allowable clock rates, supply sequencing, and timing margins, and design connector and cable interfaces to preserve controlled differential impedance.
推荐
Medical Monitoring Displays
The DS90CF562MTD is applicable to the display side of medical monitoring equipment when the chosen panel supports the compatible 18-bit color LVDS link. Differential data transfer can help maintain signal integrity across internal cable assemblies and keep common-mode noise away from sensitive measurement circuitry. The interface IC itself handles display transport rather than acquiring or processing patient data, so system isolation and clinical-safety duties remain with the complete instrument architecture. Validate the commercial temperature grade, operating limits, display timing, and fault conditions in the manufacturer datasheet before using the device in a medical product.
推荐
Point-of-Sale Terminal Displays
DS90CF562MTD suits a point-of-sale terminal in which a graphics engine feeds a compact LVDS-capable display. The 48-pin TSSOP package provides a reasonable footprint for a compact controller board, while the three differential data streams and parallel phase-locked clock support a structured connection between electronics that may be separated by a short internal cable. Designers should confirm the retail display controller’s data grouping, connector wiring, and supported refresh timing. Controlled-impedance routing, solid ground references, and separation from switching regulators are essential to prevent visible artifacts on the panel.
推荐
Embedded Human-Machine Interfaces
The DS90CF562MTD can be used in an embedded human-machine interface that connects a system-on-module or graphics controller to an LVDS display. Differential signaling is useful when the panel is physically separated from high-current processing circuitry and may be reached through an internal harness. The family’s phase-locked transmit-clock arrangement helps preserve the relationship between serialized display data and timing. Integration requires exact agreement with the display module’s supported resolution, bit mapping, synchronization inputs, and connector pinout. Follow the manufacturer reference circuit and timing tables rather than treating the family-level description as a complete electrical specification.
推荐
Automotive Information Displays
DS90CF562MTD may be considered for the receiving portion of a legacy automotive information-display link when the vehicle platform uses the compatible National Semiconductor interface. LVDS differential signaling supports robust communication across internal vehicle harnesses where noise, vibration, and ground differences can affect display links. The device is identified as commercial grade, and the listed part is marked RoHS non-compliant, so automotive qualification, temperature range, and regulatory requirements need separate confirmation before production use. Validate startup, display timing, connector retention, and error-state behavior against the manufacturer documentation.

设计说明
Route every LVDS differential pair as a controlled-impedance structure with closely matched length and geometry. Keep the three data lanes and parallel clock path away from switching nodes and high-current return paths. The package drawing and manufacturer reference circuit should determine whether the parallel clock connection requires controlled-impedance routing. Do not convert either member of the DS90CF561/DS90CF562 family into a generic single-ended display link by changing connector assignments.
Validate signal timing with the panel, graphics source, cable or connector, and intended refresh rate in the complete system. The family description confirms three LVDS streams and a phase-locked transmit clock, but maximum data rate, output differential swing, clock tolerances, and setup or hold requirements must be taken from the manufacturer datasheet. Use the specified bypass and termination network without substituting values based only on the 18-bit color designation.
Do not treat DS90CF561 and DS90CF562MTD as interchangeable drop-in parts. The former is identified as the transmitter and the latter is the receiver-side ordering code; matching the family name alone does not match direction, pin function, or PCB placement. Confirm the exact device role from the manufacturer pin-description table, and verify all supply, timing, and termination requirements before substituting any component.
Follow the manufacturer’s recommended supply network and bypass-component placement for the exact package. Place input and output bypass capacitors close to their associated pins, use short ground returns, and avoid routing display signals beneath the device between power planes unless the reference stack-up explicitly supports it. Because the exact supply range and current are not stated here, do not choose capacitors or a regulator from family-level information alone.
