THC63LVD103D

Overview

The THC63LVD103D is a single LVDS transmitter manufactured by THine Solutions, Inc., designed for pixel data transmission between host systems and flat panel displays. It converts 35 bits of CMOS/TTL input data into Low Voltage Differential Signaling (LVDS) streams. The device supports dot clock frequencies ranging from 8MHz to 160MHz, accommodating resolutions from NTSC up to 1080p at 60Hz. At the maximum 160MHz clock rate, it transmits 30 bits of RGB data and 5 bits of timing control signals (HSYNC, VSYNC, DE, CNTL1, CNTL2) at an effective rate of 1.12Gbps per LVDS channel. The component operates on a single 3.3V supply and utilizes a 64-pin TQFP package.

Feature Summary

• Integrates a PLL requiring no external components for clock generation
• Supports spread spectrum clocking and on-chip jitter filtering
• Configurable for rising or falling edge clock operation via dedicated pin
• Enables reduced swing LVDS output to minimize electromagnetic interference

Applications

• Flat panel display interfaces supporting NTSC through 1080p resolutions
• Video signal transmission for VGA, SVGA, XGA, SXGA, and SXGA+ standards
• Host-to-display pixel data links in consumer electronics

Procurement Notes

Verify manufacturer authenticity as the part may be listed under different distributor codes. Confirm package integrity upon receipt, as the 64-TQFP form factor requires careful handling. Check for end-of-life notifications, as some sources indicate discontinuance status. Ensure voltage specifications match system requirements before integration.

Selection Notes

Select this component when interfacing CMOS/TTL video sources with LVDS-capable displays. It serves as a direct replacement for the THC63LVD103 due to pin compatibility. Consider the 160MHz bandwidth limit for high-resolution applications. Verify that the system can accommodate the single 3.3V power requirement and TQFP footprint constraints.

Part Context

This transmitter belongs to THine's LVDS interface family, specifically engineered for color video transmission. It complements receiver models like the THC63LVD104 series. The device bridges digital video processors with LCD panels, replacing older parallel interface methods. Its design focuses on reducing EMI and simplifying board layout through integrated clock management features.

Replacement Considerations

The THC63LVD103 is a pin-compatible alternative within the same product line. Verify functional equivalence regarding clock edge selection and data width configuration before substitution.
