AD8192ACPZ

Overview

The AD8192ACPZ is a 2:1 HDMI/DVI switch with equalization and DDC/CEC buffers. It supports data rates up to 2.25 Gbps and pixel clocks up to 225 MHz. The device features fully buffered unidirectional inputs/outputs, switchable 50 Ω on-chip input terminations, and equalized inputs with pre-emphasized outputs. It includes bidirectional and cascadable DDC buffers with logic level translation for 3.3 V and 5 V systems, as well as a CEC buffer with integrated pull-up resistors. Powered by 3.3 V and 5 V supplies, it operates from -40°C to +85°C in a 56-lead LFCSP package.

Feature Summary

• Supports 2:1 switching of HDMI or DVI single-link sources with equalized TMDS inputs and pre-emphasized TMDS outputs.
• Includes bidirectional buffering for the DDC bus and CEC line with integrated pull-ups and logic level translation.
• Features switchable 50 Ω on-chip input terminations with programmable or automatic control during channel switching.
• Provides hot plug detect pulse low on channel switch and output disable feature for reduced power dissipation.

Applications

• Front panel buffer for advanced television (HDTV) sets
• Standalone HDMI switcher
• Multiple input displays
• Projectors
• A/V receivers

Procurement Notes

Verify the specific ordering suffix ACPZ corresponds to the 56-lead LFCSP package and RoHS compliance status required for your design. Confirm that the I2C address configuration via the I2C_ADDR pin aligns with your system's bus topology. Ensure supply voltages match the specified 3.3 V and 5 V ranges for optimal performance and thermal management within the operating temperature range.

Selection Notes

Select this component when designing systems requiring long cable runs due to its integrated receiver equalizer and transmitter pre-emphasis capabilities. It is suitable for applications needing isolation of the DDC and CEC lines to improve system capacitance limits. Consider its 2:1 switching architecture for setups connecting two sources to a single display without external multiplexing components.

Part Context

The AD8192 belongs to Analog Devices' HDMI/DVI switch family, designed for high-speed video signal routing. It complements other video interface solutions by providing complete link switching with signal integrity enhancements. The device integrates auxiliary functions like DDC and CEC buffering, reducing the need for separate logic components in consumer electronics and professional AV equipment designs.

FAQ

How does the AD8192 handle input termination during channel switching?

The AD8192 supports both manual and automatic control of its switchable 50 Ω on-chip input terminations. In automatic mode, the selected input has all terminations enabled while the deselected input has them disabled, updating automatically upon switching.

What is the function of the CEC buffer in the AD8192?

The AD8192 includes a bidirectional and cascadable CEC buffer with integrated pull-up resistors. This isolates and buffers the Consumer Electronics Control line, improving total system capacitance limits and ensuring reliable communication between devices.
