MAX3816ACUE+, Специализированный интерфейс, I2C

The MAX3816ACUE+ is an I2C 2-wire extender for DDC in DVI, HDMI and VGA interfaces in 16 pin TSSOP package. The 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 hold off period of 2.5µs prevents a subsequent state change while the cable channel settles. Under full load at 100Kbps, the MAX3816A consumes 25mW excluding pull-up resistors.

• Supply voltage range is 3V to 5.5V
• Operating temperature range from 0°C to 70°C
• DDC or I2C cable extension up to 60meters at 100Kbps for both clock and data channels
• Single-sided solution requires only one MAX3816A at the display side
• Parallel and serial operating modes
• Prevents ringing due to reflections by terminating transmission line impedance after transitions
• Use with MAX3815 TMDS equalizer to form a complete digital video extension solution
• Optional voltage translation between 5V cable DDC and 3.3V display DDC levels
