Product details
Overview
DS34RT5110SQ/NOPB from Texas Instruments is a 10.2 Gbps HDMI/DVI retimer IC with integrated input equalization and output de-emphasis, supporting three TMDS data channels and one clock channel at up to 3.4 Gbps per channel. It features dedicated CDR per data channel, <0.10 UI total output jitter at 3.4 Gbps, and resistor-adjustable differential output voltage for AC/DC-coupled Cat5e/Cat6 or HDMI cable extension in video routing systems.
For engineers reviewing the DS34RT5110SQ/NOPB datasheet, DS34RT5110SQ/NOPB pinout, DS34RT5110SQ/NOPB application, or DS34RT5110SQ/NOPB equivalent, this device is selected for high-fidelity multi-hop HDMI signal regeneration, long-reach source/sink interface conditioning, and low-jitter clock-data recovery in professional AV distribution equipment requiring stable 3.3 V operation and WQFN-48 packaging.
Technical Context
The DS34RT5110SQ/NOPB implements independent CDRs per TMDS data channel, each digitally interpolating sampling clock edges from a shared high-performance PLL on the clock channel. Its equalizer supports eight programmable boost levels (0–27 dB) via EQ[2:0] pins, while output de-emphasis offers four selectable levels (0, −3, −6, −9 dB) via DE[1:0]. The PLL loop bandwidth scales with data rate (e.g., 2.25 MHz at 2.25 Gbps), enabling deterministic jitter suppression across 250 Mbps–3.4 Gbps.
Each channel uses CML I/O with on-chip 50 Ω input termination to VDD and open-collector outputs. Output differential voltage (VO) is set by external resistor on VOD_CRL pin (24 kΩ for DC-coupled, 12 kΩ for AC-coupled), delivering 800–1200 mVp-p. Signal Detect (SD) and LOCK status pins provide real-time channel health monitoring for system-level fault handling.

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 DS34S400 | Single-channel 3.4 Gbps retimer; no integrated clock channel PLL; requires external clock source. | Suitable only for point-to-point extensions where clock regeneration is handled externally. | Select DS34S400 when system already provides low-jitter clock reference and only data-channel retiming is needed. |
| Maxim MAX3815 | 4-channel 1.65 Gbps retimer; max 0.15 UI jitter at 1.65 Gbps; no programmable de-emphasis; 0 °C to +85 °C range. | Limited to 1080i/720p; lacks HDMI v1.3a 10.2 Gbps support and multi-hop jitter performance. | Choose MAX3815 only for cost-sensitive legacy HD-SDI hybrid interfaces requiring industrial temperature range. |
Compared with DS34RT5110SQ/NOPB, DS34S400 reduces system BOM count where clock synthesis is centralized, while MAX3815 trades bandwidth and jitter performance for wider temperature tolerance-neither matches DS34RT5110SQ/NOPB's 10.2 Gbps aggregate throughput, per-channel CDR, or multi-hop signal fidelity.

FAQ
What is the maximum supported data rate per channel for DS34RT5110SQ/NOPB?
The DS34RT5110SQ/NOPB supports up to 3.4 Gbps per TMDS data channel, enabling full 10.2 Gbps aggregate throughput for HDMI v1.3a and DVI v1.0 applications including 1080p with 48-bit deep color. This rate is validated across the full operating temperature range (0 °C to +70 °C) and confirmed in TI's SNLS310G datasheet Section 6.5.
How does DS34RT5110SQ/NOPB handle jitter reduction in multi-hop configurations?
DS34RT5110SQ/NOPB reduces jitter accumulation in multi-hop setups via dedicated per-channel CDRs and a low-jitter PLL clock channel. Total output jitter remains ≤0.09 UI at 2.25 Gbps and ≤0.10 UI at 3.4 Gbps, allowing ≥3 devices to be cascaded without violating HDMI timing budgets-verified in TI application note SNLA207.
Can DS34RT5110SQ/NOPB be used with AC-coupled Cat6 cable, and what configuration is required?
Yes, DS34RT5110SQ/NOPB supports AC-coupled Cat6 extension. Configure VOD_CRL with 12 kΩ to ground for 1000 mVp-p output swing, add 50 Ω pull-up resistors near source outputs, and place 622 Ω pull-down resistors at sink inputs to set common-mode voltage to 3.05 V-details in SNLS310G Section 9.3.
What is the function of the MODE pin on DS34RT5110SQ/NOPB, and when should it be asserted HIGH?
The MODE pin bypasses the clock channel PLL. Assert MODE = HIGH in intermediate hops of multi-hop systems to prevent jitter accumulation from successive PLLs; retain MODE = LOW in the final hop to regenerate a clean, low-jitter clock for sink devices-as specified in SNLS310G Figure 9 and Section 8.4.
Does DS34RT5110SQ/NOPB require external loop filter components, and if so, what values are recommended?
Yes, DS34RT5110SQ/NOPB requires an external RC loop filter between LFn and LFp pins. TI specifies a 3.3 kΩ ±5% resistor in series with a 2.2 nF ±5% capacitor (SNLS310G Section 8.1). This network stabilizes the clock-channel PLL and ensures optimal jitter performance across all supported data rates.
