lenovo x1 wistron lnl-1 10303 schematic 1
Technical Specifications
Technical Summary
This Wistron Thinker-1 reference design, documented under A31101 dated March 7, 2011, is built around the Intel Sandy Bridge CPU platform paired with the Intel Cougar Point PCH. The integrated GMCH graphics core drives display outputs including LVDS, HDMI, and DisplayPort. System memory consists of two 204-pin DDR3 SODIMM slots operating at 1333MHz. The embedded controller is a VBG25HV, and the BIOS is stored on a SPI-FLASH device. Power management is handled by a TPS51220ARS system DC/DC converter, a BQ24742 battery charger/selector, and multiple VT and TPS series regulators. The audio subsystem uses an ALC269 codec, while connectivity includes an Intel LEWISVILLE WLAN card, a VT1316/VT1317 LAN controller, and a uPD720200A USB 3.0 hub controller. Thermal monitoring is provided by an EMC1428 sensor, and media card reading is managed by a Rinken controller.
