DDC Accelerator (DDCA)

Features

The ISL54103 DDC Accelerator (DDCA) is a dual active

pull-up bus terminator designed to improve data

transmission speed on the DDC 2-wire serial bus interfaces.

• Active Termination for DDC Lines

• Enhances System Bus Signal Rise Time

• More Reliable HDCP Performance In Video Multiplexers

and Cable Extenders

The DDCA detects rising input transitions with two internal

voltage references and two comparators per channel. After

the voltage on a data line crosses the first threshold

• Increases Maximum Cable Length While Guaranteeing

Data Integrity

), the boost pull-up current source is activated to

TRIPL

speed transition. After the voltage crosses the second

threshold (V ), the boost pull-up current source is

• 2.2mA Current Boost on Low to High Transitions

• 8kV ESD Protection on SDA and SCL Pins

• Wide Operating Voltage Range: 2.7V to 5.5V

• Small Package - 5 Ld SOT-23

TRIPH

de-activated, leaving an active pull-up current of 275µA on

the line. When both channels are HIGH, the pull-up current

for both lines is reduced to 100µA to save power. Internal

logic ensures that the active and boost pull-up current

sources are not activated during downward transitions.

• Pb-free Plus Anneal Available (RoHS Compliant)

The level for V

referred to V . This feature makes the switching behavior

invariant for all power supply voltages between 2.7V and

5.5V.

• Video Cable Extenders

• Video Distribution Amplifiers

• Televisions

A noise filter on each channel prevents the circuit from

responding to input transitions that do not exceed a

voltage-time threshold. To activate the boost circuit, the input

by 100Vns (typical) (See Figure 10).

The DDCA permits operation of the bus at frequencies up to

100kHz, despite the capacitive loads of multiple devices

and/or long PC board traces. Enhanced ESD protection on

the accelerator pins are guaranteed to withstand 8kV ESD

(HBM) events.

TOP VIEW

The DDC Accelerator provides an essential function in DDC

applications because of distributed capacitance of the DDC

wires in long video cables. By incorporating DDCA, systems

using DDC can reliably increase their bus load, allowing

longer cables, without the risk of data corruption.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
