AD8193ACPZ-R7

Overview

The AD8193ACPZ-R7 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 outputs to maintain signal integrity.
• Integrated 50 Ω on-chip terminations at both inputs and outputs reduce system reflections.
• Single-pin source selection logic controls switching between two input groups.
• Automatic termination switching disables the unselected input channel.

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 reel packaging configuration. Confirm the specific revision level against the latest manufacturer documentation to ensure compatibility with current design requirements. Cross-reference the pinout and thermal pad connections during the procurement validation phase.

Selection Notes

Select this component when a buffered solution is required to drive long cable runs or multiple loads without signal degradation. Ensure the application supports single-ended 50 Ω termination schemes. Verify that the control logic voltage levels align with the specified S_SEL interface thresholds before integration into the system design.

Part Context

This part belongs to Analog Devices' portfolio of high-speed video interface components. It serves as a core switching element for managing multiple HDMI or DVI sources in consumer electronics. The device complements other signal conditioning products by providing dedicated routing for high-bandwidth digital content.

Replacement Considerations

The AD8194 is documented as a pin-to-pin compatible alternative within the same product family. Verify functional equivalence regarding specific performance metrics before substituting.
