Product details
Overview
DS34RT5110SQX/NOPB from Texas Instruments is a 10.2 Gbps HDMI/DVI retimer IC with per-channel CDR, configurable input equalization (up to 27 dB boost), and output de-emphasis (0–9 dB). It supports TMDS data rates from 250 Mbps to 3.4 Gbps per channel and delivers ≤0.10 UI total output jitter at 3.4 Gbps - enabling multi-hop extension of 1080p/48-bit video over 25+ meters of 28 AWG HDMI cable.
For engineers reviewing the DS34RT5110SQX/NOPB datasheet, DS34RT5110SQX/NOPB pinout, DS34RT5110SQX/NOPB application, or DS34RT5110SQX/NOPB equivalent, this page provides verified specifications, validated pin functions, real-world HDMI/DVI repeater use cases, and two confirmed alternative retimers with documented functional trade-offs.
Technical Context
The DS34RT5110SQX/NOPB implements three independent TMDS data channels and one dedicated clock channel, each with its own CDR and programmable equalizer. Its PLL-based clock regeneration achieves <0.09 UI jitter at 2.25 Gbps and <0.10 UI at 3.4 Gbps, supporting cascaded multi-hop topologies without signal fidelity degradation.
Input equalization uses EQ[2:0] pins to select eight discrete boost levels (0–27 dB); output de-emphasis is controlled via DE[1:0] for four settings (0, –3, –6, –9 dB). The VOD_CRL pin sets differential output swing (1000 mVp-p) using external 12 kΩ (AC-coupled) or 24 kΩ (DC-coupled) resistors.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI/DVI retimer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI DS34S132 | Single 3.4 Gbps channel; no clock channel; fixed 12 dB equalization; no de-emphasis. | Limited to single-lane repeaters or point-to-point extensions; cannot support full 4-channel HDMI/DVI. | Select DS34S132 only for cost-sensitive, single-TMDS-lane applications where full 10.2 Gbps capability is unnecessary. |
| Maxim MAX3815 | 3.125 Gbps max rate; 0.12 UI jitter at 3.125 Gbps; no programmable EQ/DE; 64-pin TQFP package. | Suitable for legacy HDMI 1.2 or DVI 1.0 systems up to 2.25 Gbps; not qualified for 3.4 Gbps HDMI 1.3a 48-bit color. | Choose MAX3815 only for backward-compatible designs targeting ≤2.25 Gbps with fixed-performance requirements. |
Compared with DS34RT5110SQX/NOPB, DS34S132 lacks multi-channel support and clock regeneration, while MAX3815 falls short on data rate, jitter performance, and configurability - making DS34RT5110SQX/NOPB the only option for full-bandwidth, multi-hop, standards-compliant HDMI v1.3a retiming.
