【基本資料】

【產品特性】

• PTN3460 is an (embedded) DisplayPort to LVDS bridge device that enables connectivity between an (embedded) DisplayPort (eDP) source and LVDS display panel. It processes the incoming DisplayPort (DP) stream, performs DP to LVDS protocol conversion and transmits processed stream in LVDS format.
• Embedded microcontroller and on-chip Non-Volatile Memory (NVM) allow for flexibility in firmware updates 
• 
LVDS panel power-up (/down) sequencing control
Firmware controlled panel power-up (/down) sequence timing parameters
No external timing reference needed
• EDID ROM emulation to support panels with no EDID ROM:Supports EDID structure v1.3
• 
On-chip EDID emulation up to seven different EDID data structures
• 
eDP complying PWM signal generation or PWM signal pass through from eDP source


• Power supply: with on-chip regulator
• 3.3 V10 % (integrated regulator switched on 3.3 V 10 %, 1.8 V 5 % (integrated regulator switched off)
• ESD: 8 kV HBM, 1 kV CDM
• Operating temperature range: 0 C to 70 C
• HVQFN56 package 7 mm x 7 mm, 0.4 mm pitch; exposed center pad for thermal relief and electrical ground


【產品應用】

• AIO platforms
• Notebook platforms
• Netbooks / net tops

【文字介紹】

The PTN3460 can receive DP stream at link rate 1.62 Gbit/s or 2.7 Gbit/s and it can support 1-lane or 2-lane DP operation. It interacts with DP source via DP Auxiliary (AUX) channel transactions for DP link training and setup.
It supports single bus or dual bus LVDS signaling with color depths of 18 bits per pixel or 24 bits per pixel and pixel clock frequency up to 112 MHz. The LVDS data packing can be done either in VESA or JEIDA format. Also, the DP AUX interface transports I²C-over-AUX commands and support EDID-DDC communication with LVDS panel. To support panels without EDID ROM, the PTN3460 can emulate EDID ROM behavior avoiding specific changes in system video BIOS.
