What are the key features of TMDS461PZT?
- 4-to-1 HDMI and DVI input multiplexing enabling a single display to switch between up to 4 source devices without external signal conditioning
- 100-pin TQFP package (0.63 mm pitch) with HDMI-compliant TMDS signaling path supporting high-definition video up to 1080p resolution
- Consumer-grade single-function IC with lead-free plastic TQFP construction suited for TV, monitor, and AV receiver HDMI switch-matrix designs
What is TMDS461PZT used for?
The TMDS461PZT is designed for consumer display systems including televisions, AV receivers, and desktop monitors that must accept HDMI or DVI video signals from up to 4 source devices such as set-top boxes, Blu-ray players, gaming consoles, and PCs. Its integrated 4-to-1 switch removes the need for discrete TMDS multiplexer solutions, reducing BOM cost and PCB area in compact display controller boards. The device is also suited for professional presentation switchers and conference-room AV systems where multiple HDMI sources share a single projector or panel output.

Frequently Asked Questions
How many HDMI sources can TMDS461PZT switch, and what video resolutions does it support?
The TMDS461PZT supports 4 HDMI or DVI input sources routed to 1 output, allowing a single display to receive signals from 4 separate devices. Its TMDS (Transition Minimized Differential Signaling) architecture is compatible with HDMI 1.x high-definition resolutions up to 1080p at 60 Hz, which meets the display requirements of most consumer televisions, monitors, and projectors without external re-clocking hardware.
For a television design, how does the TMDS461PZT reduce BOM complexity compared to a discrete HDMI switch solution?
A discrete TMDS switch solution for 4 HDMI inputs requires separate multiplexer ICs, ESD protection arrays, and level-shifting circuitry for each differential pair, often consuming 4 to 6 ICs and 20 or more passive components. The TMDS461PZT integrates all 4-to-1 switching functions in a single 100-pin TQFP, cutting the HDMI switch section of a TV motherboard to one device, reducing both solder joint count and the firmware state-machine needed to coordinate multiple discrete switches.
What package does TMDS461PZT use, and how does the pin pitch affect PCB routing for HDMI differential pairs?
The TMDS461PZT uses a 100-pin TQFP (PQFP-G100) with a 0.63 mm fine-pitch lead spacing. Routing HDMI TMDS differential pairs at 0.63 mm pitch requires controlled-impedance 100-ohm differential trace routing on an inner PCB layer, typically on a 6-layer stackup, to maintain signal integrity up to the 1080p video clock frequency of approximately 148.5 MHz.
In a conference-room AV system, when is TMDS461PZT a better choice than a full HDMI matrix switch?
When a conference room has exactly 4 HDMI sources (laptop, desktop PC, video conferencing unit, Blu-ray) and a single projector output, the TMDS461PZT's 4-to-1 single-output architecture matches the topology precisely, avoiding the cost and complexity of an N×M HDMI matrix switch that routes any input to any of multiple outputs. The single-chip solution also simplifies the control-path firmware to a 2-bit source-select signal, reducing software development time compared to programming a full matrix switch controller over I2C or RS-232.
