MAX3816A
I²C 2-Wire Extender for DDC in DVI, HDMI, and VGA Interfaces
Extend DVI/HDMI Reach Beyond 30m
|
Status
Active: In Production.
Description
The MAX3816A DDC*/I²C extender automatically compensates for excess load capacitance of long DVI™, HDMI™, and VGA cables. A single MAX3816A placed at the display side of the link restores signal integrity bidirectionally for both DDC clock and data over 0 to 60 meters of cable.
The MAX3816A features compensation for cable capacitance with a guaranteed range up to 3000pF, typically beyond 5000pF. The MAX3816A detects state-change assertion by the logical "AND" of the source side and display side. It asserts the new state with a rail-to-rail slew-rate-limited driver capable of meeting I²C rise- and fall-time requirements under the full load of the cable. After assertion of the new state, a holdoff period of 2.5µs prevents a subsequent state change while the cable channel settles.
Under full load at 100kbps, the MAX3816A consumes 25mW, excluding pullup resistors. It is available in a 16-pin TSSOP package and operates from 0°C to +70°C.
