AD8193ACPZ

Overview

The AD8193ACPZ is a buffered quad 2:1 TMDS switch designed for high-speed HDMI and DVI video applications. It switches signals from two single-link sources to one output, supporting data rates up to 2.25 Gbps and pixel clocks up to 225 MHz. The device features fully buffered unidirectional inputs and outputs with matched 50 Ω on-chip terminations to minimize reflections. It operates on a single 3.3 V supply and includes low added jitter specifications of 25 ps peak-to-peak deterministic jitter and 1 ps RMS random jitter. The component is housed in a 32-lead, 5 mm × 5 mm LFCSP package.

Feature Summary

• Fully buffered architecture isolates input channels from the output to maintain signal integrity.
• Integrated 50 Ω input and output terminations absorb reflections and improve system performance.
• Single-pin source selection logic controls switching between two input groups.
• Automatic termination switching disables unused input terminations to reduce power consumption.

Applications

• Advanced television (HDTV) sets
• Multiple input displays
• Projectors
• A/V receivers
• Set-top boxes

Procurement Notes

Verify that the ordering suffix matches the required package type and temperature range. Confirm RoHS compliance status as specified in the manufacturer's documentation. Ensure the supplier provides original manufacturer packaging to prevent counterfeit components. Cross-reference the part number with official distributor catalogs to validate authenticity before purchase.

Selection Notes

Select this component when designing systems requiring a buffered switch for HDMI or DVI signals. It is suitable for applications needing support for deep color formats and resolutions greater than UXGA. Consider using complementary CMOS switches for low-speed DDC channel switching, as this device handles only high-speed TMDS signals.

Part Context

This component belongs to Analog Devices' portfolio of high-speed video interface solutions. It serves as a key building block for multi-source display systems. The device enables seamless integration of various digital video sources into a single display output while maintaining strict signal quality standards required by modern video protocols.

Replacement Considerations

The AD8194 is a pin-to-pin compatible alternative within the same product family. Verify functional equivalence regarding specific application requirements before substitution. Ensure that any replacement maintains the necessary data rate and buffering characteristics.
