DESCRIPTION

· The ISL54103 DDC Accelerator (DDCA) enhances data transmission speed on DDC 2-wire serial bus interfaces.
· It uses dual active pull-up bus termination with internal voltage references and comparators.
· Activates boost pull-up current source when voltage crosses VTRIPL, deactivates at VTRIPH.
· Maintains 275µA active pull-up current, reduces to 100µA when both channels are HIGH.
· Operates reliably across a power supply range of 2.7V to 5.5V.
· Features noise filters to prevent false triggering.
· Supports bus frequencies up to 100kHz, even with high capacitive loads.
· Provides 8kV ESD protection on SDA and SCL pins.
· Ideal for applications with long video cables and distributed capacitance.

FEATURES

· Active termination for DDC lines.
· Enhances system bus signal rise time.
· Improves HDCP performance in video multiplexers and cable extenders.
· Increases maximum cable length while ensuring data integrity.
· Provides 2.2mA current boost on low-to-high transitions.
· Wide operating voltage range: 2.7V to 5.5V.
· Compact 5-lead SOT-23 package.
· Pb-free and RoHS compliant.

APPLICATIONS

· Video multiplexers.
· Video cable extenders.
· Video distribution amplifiers.
· Televisions.
