1.

VAUX-DIFFp-p = 2*|VAUXP – VAUXM|. Refer to the VESA DisplayPort Standard specification for more 

details.

2.

COMP resistance must be provided on the system board with 1% resistors. COMP resistors are to V

SS

.

3.

eDP_ICOMPO, eDP_ICOMPI, eDP_RCOMPO are the same resistor.

PECI is an Intel proprietary interface that provides a communication channel between 
Intel processors and chipset components to external Adaptive Thermal Monitor devices. 
The processor contains a Digital Thermal Sensor (DTS) that reports a relative die 
temperature as an offset from Thermal Control Circuit (TCC) activation temperature. 
Temperature sensors located throughout the die are implemented as analog-to-digital 
converters calibrated at the factory. PECI provides an interface for external devices to 
read the DTS temperature for thermal management and fan speed control. More 
detailed information may be found in the Platform Environment Control Interface 
(PECI) Specification.

The PECI architecture based on wired OR bus that the clients (such as 2nd Generation 
Intel

®

 Core™ processor family mobile PECI) can pull up high (with strong drive).

The idle state on the bus is near zero.

 demonstrates PECI design and connectivity, while the host/originator can be 

3rd party PECI host, and one of the PECI client is a 2nd Generation Intel
