Product details
Overview
TMDS361PAGR from Texas Instruments is a 3-to-1 HDMI/DVI switch IC for high-definition video routing in sink-side HDTV systems, supporting up to 1080p resolution at 3 Gbps data rate, 16-bit color depth, and adaptive equalization for up to 20-m HDMI cables. It integrates TMDS clock detection, DDC repeater functionality, and robust 10 kV HBM ESD protection on all TMDS, DDC, and HPD pins.
For engineers reviewing the TMDS361PAGR datasheet, TMDS361PAGR pinout, TMDS361PAGR application, or TMDS361PAGR equivalent, this device serves as a critical interface component in HDMI-enabled display terminals requiring automatic power management, source selection via I²C or GPIO, and compliance with HDMI 1.3a and DVI 1.0 specifications.
Technical Context
The TMDS361PAGR implements a 3:1 multiplexer architecture with three independent TMDS input ports (each with CLK± and D[0:2]±) and one unified TMDS output port (CLK±_SINK and D[0:2]±_SINK), plus integrated 50-Ω terminations switched per active port. Its adaptive equalizer dynamically compensates for intersymbol interference across cable lengths up to 20 dB loss at 3 Gbps.
Control is implemented via dual-mode interface: I²C slave mode (I2C_SEL = LOW) enables full register access for edge-rate tuning, DDC buffer OVS selection, and clock-detect bypass; GPIO mode (I2C_SEL = HIGH) uses S1/S2 logic inputs for port selection and LP pin for low-power entry. Hot-plug detect outputs (HPD1–HPD3) mirror HPD_SINK state for selected port only.

Pinout & Package
TMDS361PAGR is housed in a 64-pin TQFP (PAG package), 10 mm × 10 mm, 0.5 mm pitch, RoHS-compliant, with exposed thermal pad. Pin functions are validated per TI SLLS919A datasheet Rev. January 2009.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+_1 / CLK–_1 D[0:2]+_1 / D[0:2]–_1 |
Port-1 TMDS differential clock and data inputs | Accepts compliant/non-compliant HDMI/DVI signals; common-mode range extends to VCC + 0.01 V |

|---|---|
| Adaptive equalization | Automatically adjusts gain to compensate for ISI loss up to 20 dB at 3 Gbps - eliminates manual EQ tuning across cable lengths |
| TMDS clock-detect circuit | Enables automatic power gating: disables TMDS data-line terminations and places outputs in high-Z when no valid clock is present |
| VSadj-controlled output swing | External 4.02 kΩ resistor sets TMDS-compliant differential output voltage (800–1200 mVpp) - aids HDMI compliance testing |
| DDC repeater with OVS selection | Three programmable low-level output voltage settings (OVS1–OVS3) optimize sink-side DDC noise margin and rise time |
| Robust receive stage | Accepts TMDS input common-mode voltages from VCC – 0.4 V to VCC + 0.01 V - interoperates with non-compliant sources |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI/DVI switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMDS351PAGR | Pin-compatible 3:1 switch but lacks adaptive equalization and supports max 1.65 Gbps - no 1080p@60Hz Deep Color support | Targeted at legacy DVI-only or 720p systems; insufficient for HDMI 1.3a 3 Gbps compliance | Select TMDS351PAGR only if cost sensitivity outweighs 1080p/Deep Color requirement and cable runs are ≤5 m |
| PI3HDX1204ZLEX | 4:1 HDMI 2.0 switch with 6 Gbps capability; requires 1.8-V I/O and separate 3.3-V analog supply; no built-in DDC repeater | Designed for UHD/4K systems with higher bandwidth and different power architecture | Choose PI3HDX1204ZLEX only when upgrading to 4K/60Hz and redesigning power delivery and layout |
Compared with TMDS351PAGR, TMDS361PAGR adds adaptive equalization and 3 Gbps support essential for 1080p Deep Color; versus PI3HDX1204ZLEX, it offers simpler single-supply operation and integrated DDC repeater but lacks 4K readiness - making TMDS361PAGR optimal for cost-sensitive, HDMI 1.3a–compliant 1080p sink designs.

FAQ
What is the maximum supported data rate for TMDS361PAGR?
The TMDS361PAGR supports signaling rates up to 3 Gbps, enabling full 1080p resolution with 16-bit color depth and Deep Color in HDMI 1.3a–compliant systems. This rate is validated across all three input ports and the unified output path, with adaptive equalization maintaining signal integrity over extended cable lengths.
Does TMDS361PAGR require external termination resistors?
No, TMDS361PAGR integrates 50-Ω termination resistors on all TMDS clock and data lines. These are automatically enabled per selected input port and disabled for inactive ports, eliminating the need for external terminations and reducing PCB footprint and BOM count.
How does the TMDS clock-detect feature function in TMDS361PAGR?
In TMDS361PAGR, the clock-detect circuit monitors incoming TMDS clock signals. When no valid clock is detected, it disconnects input data-line terminations and places TMDS outputs in high-impedance state - reducing power consumption by ~170 mA in normal mode. Detection is active by default and can be bypassed via I²C command for HDMI compliance testing.
Can TMDS361PAGR operate with non-compliant HDMI source devices?
Yes, TMDS361PAGR features a robust TMDS receive stage that accepts input common-mode voltages from VCC – 0.4 V to VCC + 0.01 V, allowing interoperability with HDMI/DVI sources that fall outside strict specification limits - a key advantage in real-world consumer electronics integration.
What is the role of the VSadj pin on TMDS361PAGR?
The VSadj pin on TMDS361PAGR connects to an external 4.02 kΩ ±10% resistor to set the TMDS output differential voltage swing between 800 mVpp and 1200 mVpp. This precision adjustment ensures compliance with HDMI 1.3a output voltage requirements and supports system-level validation testing.
