PTN3355

Low power DP to VGA adapter with integrated 1 : 2 VGA switch

13. Characteristics

13.1 Current consumption, power dissipation and thermal characteristics

[1]

VGA monitor remains connected at power-on — this condition is applicable only when PTN3355 is used in most interoperable

(non-compliant) HPD mode (that is, CFG1_SCL/CFG2_SDA is ‘01’ or ‘10’).
