AD8192ACPZ-RL7

Overview

The AD8192ACPZ-RL7 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 (3.3 V, 5 V) and a CEC buffer with integrated pull-up resistors. The component operates over a temperature range of −40°C to +85°C and is housed in a 56-lead, 8 mm × 8 mm LFCSP package.

Feature Summary

• Supports HDMI 1.3a receive and transmit compliance with ±7 kV HBM ESD protection on input pins.
• Features equalized TMDS inputs and pre-emphasized TMDS outputs for long cable run compensation.
• Includes bidirectional and cascadable DDC buffers with logic level translation and a CEC buffer with integrated pull-ups.
• Provides hot plug detect pulse low on channel switch and an 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-RL7 against the manufacturer's current datasheet to confirm tape-and-reel packaging and lead-free status. Ensure the I2C address configuration via the I2C_ADDR pin aligns with system requirements. Confirm thermal management strategies for the LFCSP package are adequate for the intended operating environment.

Selection Notes

Select this component for applications requiring signal integrity preservation over extended cable lengths due to its built-in receiver equalizer and transmitter pre-emphasis capabilities. The inclusion of auxiliary switches isolates and buffers the DDC bus and CEC line, improving total system capacitance limits. Consider the serial control interface for flexible manual or automatic switching modes.

Part Context

The AD8192 is part of Analog Devices' HDMI/DVI switch family designed for high-speed video routing. It complements other devices like the AD8197 by offering a 2:1 configuration rather than 4:1. The device integrates both high-speed TMDS switching and low-speed auxiliary signal buffering into a single compact surface-mount package.

Replacement Considerations

Check for direct substitutes within the ADI portfolio such as the AD8197 for higher port counts. Verify compatibility with existing PCB layouts and I2C addressing schemes when considering alternative HDMI switches from other manufacturers.

FAQ
