Product details
Overview
STDVE103ABTR from STMicroelectronics is a 3.4 Gbps adaptive TMDS/HDMI 3:1 signal equalizer and switch IC, integrating four 3.4 Gbps differential channels, on-die 50 Ω input termination, fully automatic equalization for cables up to 25 m, and I²C DDC repeater functionality. It operates at −40°C to +85°C in TQFP64 package and is deployed in HDMI source selection paths of advanced TVs and set-top boxes to restore degraded high-speed video signals before HDMI receiver input.
For engineers reviewing the STDVE103ABTR datasheet, STDVE103ABTR pinout, STDVE103ABTR application, or STDVE103ABTR equivalent, key selection criteria include its 340 MHz clock support for deep-color video, 5.3 V-tolerant DDC/HPD I/Os, lock-up free I²C bus operation up to 400 kHz, low output skew (<15 ps), and integrated open-drain DDC buffer - all critical for HDMI v1.3 compliance and long-cable signal integrity.
Technical Context
The device implements a fully adaptive analog equalizer with frequency-dependent gain (3 dB at 225 MHz, 16 dB at 1650 MHz) to compensate intersymbol interference from lossy HDMI cables. Its 3:1 switch architecture uses SPDT-type routing for all four TMDS channels (data + clock), with independent HPD and DDC path switching per port.
It integrates an I²C DDC repeater supporting bidirectional 0–400 kHz communication, 5.3 V-tolerant SDA/SCL/HPD pins, and selectable 50 Ω input termination referenced to VCC (3.135–3.465 V). The output driver is current-mode with flow-through pinout to minimize internal jitter and propagation delay skew across channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI signal conditioning and switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TDP142 | Single-port 3.4 Gbps redriver (no switching); requires external MUX; no integrated DDC repeater | Best for point-to-point signal boost only; not suitable for multi-source selection | Select when only signal regeneration is needed and source switching is handled elsewhere |
| Pericom PI3HDX1204A | 4-channel 3.4 Gbps HDMI switch without adaptive equalization; fixed-gain architecture | Limited to short-cable (<5 m) applications; cannot compensate variable cable loss | Select for cost-sensitive designs with known short interconnects and no long-cable requirement |
Compared with TDP142 and PI3HDX1204A, STDVE103ABTR uniquely combines adaptive equalization, 3:1 switching, and DDC/HPD routing in one TQFP64 package - eliminating external MUX, level shifters, and termination resistors required by alternatives.

FAQ
What is the function of the REXT pin on STDVE103ABTR?
The REXT pin connects to ground via a 4.7 kΩ ±1% precision resistor to set the output current of the TMDS drivers. This ensures compliant TMDS output voltage swing (typically 300–600 mVpp) across process, voltage, and temperature variations. Incorrect REXT value causes non-compliant output levels and potential HDMI link failure.
Does STDVE103ABTR require external 50 Ω termination resistors on TMDS inputs?
No. STDVE103ABTR integrates precise 50 Ω ±5% termination resistors on all TMDS input channels, referenced to VCC. External termination is unnecessary and would cause double-termination, leading to signal reflection and eye closure. Board layout must avoid adding parallel resistors.
How does the adaptive equalizer respond to different cable lengths?
The equalizer automatically adjusts gain across frequency (225–1650 MHz) based on real-time signal analysis, delivering 3 dB boost at 225 MHz and up to 16 dB at 1650 MHz. This compensates for increasing high-frequency attenuation in cables from 1 m to 25 m without firmware or register writes.
Can STDVE103ABTR operate with 5 V I/O supplies for DDC/HPD while using 3.3 V for TMDS core?
Yes. STDVE103ABTR has dual supplies: VCC (3.135–3.465 V) powers TMDS core and termination, while VDD (4.5–5.5 V) powers DDC, HPD, and SEL pins. The 5.3 V-tolerant I/O structure allows direct connection to 5 V DDC masters without level shifters, simplifying interface design.
