Overview
The AD8194ACPZ is a buffered 2:1 TMDS switch designed for high-speed HDMI and DVI video applications. It features four TMDS channels per input/output, supporting data rates from 250 Mbps to 2.25 Gbps and pixel clocks up to 225 MHz. The device includes equalized inputs capable of compensating for cable loss over distances exceeding 20 meters at maximum data rates. It operates on a single 3.3 V supply with typical quiescent currents of 70 mA (AVCC), 54 mA (VTTI), and 65 mA (VTTO). The component provides matched 50 Ω on-chip terminations and low added jitter (10 ps deterministic, 1 ps random) to ensure signal integrity. It is housed in a 32-lead LFCSP package.
Feature Summary
- Fully buffered unidirectional inputs and outputs with integrated 50 Ω terminations
- Input cable equalization supports long HDMI cable runs up to 2.25 Gbps
- Single-pin source selection logic for switching between two HDMI/DVI sources
- Low added jitter performance for improved system signal integrity
Applications
- Advanced television (HDTV) sets
- Multiple input displays
- Projectors
- A/V receivers
- Set-top boxes
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and environmental compliance. Ensure that the procurement channel provides valid traceability for Analog Devices components. Confirm availability status directly with authorized distributors as stock levels fluctuate.
Selection Notes
Select this component when a fully buffered 2:1 TMDS switch with input equalization is required for HDMI or DVI signals. It is suitable for designs needing to extend cable lengths beyond standard limits without external equalizers. Verify that the application requires only high-speed signal switching, as low-speed DDC signals require separate handling.
Part Context
The AD8194 is part of Analog Devices' portfolio of high-speed video interface solutions. It serves as a pin-to-pin compatible alternative to the AD8193, offering similar functionality within the same LFCSP form factor. This integration allows for straightforward design upgrades in existing HDMI/DVI routing architectures.
Replacement Considerations
The AD8193 is a pin-to-pin compatible substitute. Verify that the replacement meets all electrical specifications for the target data rate and voltage requirements before implementation.
