Spesifikasi
This is a dual-link LVDS serializer chip developed by THine Electronics, which converts parallel RGB TTL video signals into low-voltage differential LVDS serial streams, designed for high-resolution LCD panels up to 1080P and QXGA specifications to reduce wiring quantity and electromagnetic interference on display boards.
Part Number Definition
THC63LVD823B is the upgraded version of the classic 823 series LVDS transmitting chip, optimizing signal mapping and EMI suppression functions, and maintaining backward compatibility with earlier model codes.
Core Function and Electrical Parameters
The chip adopts dual-channel parallel data input architecture, receiving two groups of 24-bit RGB parallel signals together with line sync, field sync and data enable signals, and integrates an internal PLL clock circuit without extra peripheral oscillator components. The input dot clock frequency ranges from 10MHz to 160MHz, supporting maximum pixel throughput of 320 million pixels per second, with each LVDS differential channel reaching 1.12Gbps transmission rate. It outputs two groups of 4-channel LVDS differential data plus dedicated differential clock signal, supporting single-link and dual-link working modes freely switched via hardware pins. Input pins tolerate 1.2V to 3.3V logic level, which can be directly connected to low-voltage main control processors. A reduced swing LVDS output mode is built in to lower radiation interference during high-speed transmission. It provides hardware pin to select rising or falling edge data sampling, and adds pseudo-random test signal generation function for production debugging. The single power supply works at 3.3V, with independent power-down pin to enter ultra-low power standby state when the display is off.
Packaging and Assembly Specifications
Standard package is 100-pin TQFP surface mount form factor with overall dimension 14mm×14mm. It is classified as MSL3 moisture sensitive device, and reflow soldering procedures must be finished within 168 hours after opening vacuum packaging. Tray and tape-and-reel packaging options are available to match automatic SMT assembly on production lines.
Environmental and Compliance Standards
Industrial grade operating temperature range is -40℃ to +85℃, adapting to television equipment, industrial display terminals and vehicle-mounted display working environments. The product is lead-free and complies with standard environmental restriction requirements. Differential signal transmission greatly simplifies PCB wiring layout and improves signal transmission stability for long-distance board-level connection.
