Product details
Overview
DS22EV5110SQ/NOPB from Texas Instruments is a 6.75 Gbps DVI/HDMI extended-reach equalizer with integrated retimer and configurable output de-emphasis. It processes three TMDS data channels and one clock channel at up to 2.25 Gbps per channel, incorporates dedicated CDR per data channel, delivers ≤0.09 UI total output jitter at 2.25 Gbps, and supports 25 m of 28 AWG HDMI cable for 1080p/36-bit color. It serves as source, sink, or repeater in high-definition video extension systems.
For engineers reviewing the DS22EV5110SQ/NOPB datasheet, DS22EV5110SQ/NOPB pinout, DS22EV5110SQ/NOPB application, or DS22EV5110SQ/NOPB equivalent, key selection criteria include TMDS channel count (4-channel: 3 data + 1 clock), CDR-based jitter reduction capability, resistor-adjustable differential output voltage (800–1200 mVp-p), EQ/DE programmability via LVCMOS control pins, and WQFN-48 package compatibility with high-speed layout constraints.
Technical Context
The DS22EV5110SQ/NOPB implements independent CDRs per TMDS data channel, each with loop bandwidth ≈ bit rate / 1000 (e.g., 2.25 MHz at 2.25 Gbps), synchronized to a high-performance PLL on the clock channel. Its input equalizer offers eight programmable boost levels (0–30 dB) via EQ[2:0], while output de-emphasis provides four selectable levels (0, –3, –6, –9 dB) via DE[1:0].
It supports both DC-coupled (24 kΩ VOD_CRL) and AC-coupled (12 kΩ VOD_CRL + external biasing) TMDS interfaces, features open-collector CML outputs with 50 Ω on-chip termination at inputs, and integrates signal detect (SD) and lock (LOCK) status indicators for system-level handshaking and automatic enable control.

|---|---|
Use Scenario: Extending HDMI signal from source to display over 25 m of 28 AWG shielded cable in digital signage or AV distribution systems. IC Role / Device Role / Timing Role: Acts as active repeater-equalizing degraded input, re-timing with low-jitter CDR, and de-emphasizing output to drive long cable runs. Use Value: Enables 1080p/36-bit color transmission with ≤0.09 UI jitter, eliminating eye closure and ensuring HDMI v1.3a compliance at full reach. |
Use Scenario: Integrating into GPU or media processor board to drive HDMI outputs directly from silicon with robust cable-driving capability. IC Role / Device Role / Timing Role: Functions as HDMI source buffer-conditioning TMDS signals before connector, adding de-emphasis for trace/cable loss compensation. Use Value: Eliminates need for discrete level-shifting or external equalization; supports plug-and-play compatibility with standard HDMI displays. |
| Blu-ray Disc Player Output Stage | Game Console Video Interface |
Use Scenario: Enhancing HDMI output from Blu-ray player SoC to maintain signal integrity over consumer-grade HDMI cables up to 15 m. IC Role / Device Role / Timing Role: Operates as source-side signal conditioner-applying precise de-emphasis based on detected cable length and format (e.g., 2.25 Gbps 1080p). Use Value: Guarantees stable deep-color playback without artifacts; leverages SD/LOCK pins for automatic power-down during standby. |
Use Scenario: Embedding in game console motherboard to support high-bandwidth HDMI output for 1080p/60Hz gaming with minimal latency. IC Role / Device Role / Timing Role: Serves as low-latency retimer-CDR latency fixed at 400 ps (data) / 600 ps (clock), preserving real-time video timing. Use Value: Maintains sub-frame synchronization critical for interactive gameplay; avoids frame stutter caused by jitter-induced receiver resync. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI/DVI signal conditioning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI DS10EV016AQ/NOPB | 4-channel, 1.65 Gbps max; no CDR-only equalization; smaller 32-pin WQFN | Limited to 1080i/720p; unsuitable for 2.25 Gbps 1080p/36-bit or jitter-sensitive repeater use | Select only for cost-sensitive, lower-bandwidth HDMI sources where retiming is unnecessary. |
| Maxim MAX3815 | Single-channel, 2.5 Gbps; includes deskew; requires external reference clock; different pinout | Used in multi-chip solutions for skew-critical applications; not drop-in compatible; higher BOM complexity | Choose only when inter-pair skew correction is mandatory and system design accommodates separate clock routing and layout overhead. |
Compared with DS22EV5110SQ/NOPB, DS10EV016AQ/NOPB lacks retiming and de-emphasis-limiting reach and jitter performance-while MAX3815 adds deskew but increases design complexity and does not match the integrated 4-channel, self-contained architecture of the DS22EV5110SQ/NOPB.

FAQ
What is the maximum supported data rate per TMDS channel for DS22EV5110SQ/NOPB?
The DS22EV5110SQ/NOPB supports up to 2.25 Gbps per TMDS data channel, enabling full 1080p resolution with 36-bit deep color (6.75 Gbps aggregate). This matches HDMI v1.3a and DVI v1.0 specifications and is validated across temperature and voltage ranges per TI SNLS311E.
How does DS22EV5110SQ/NOPB reduce jitter in HDMI/DVI systems?
The DS22EV5110SQ/NOPB reduces jitter using dedicated CDR circuits per data channel that regenerate clean sampling clocks from the incoming TMDS signal. At 2.25 Gbps, it achieves ≤0.09 UI total output jitter-significantly improving eye opening and timing margin versus passive equalizers or unconditioned links.
Can DS22EV5110SQ/NOPB be used in AC-coupled HDMI applications?
Yes, DS22EV5110SQ/NOPB supports AC-coupled operation using a 12 kΩ resistor on the VOD_CRL pin and external 50 Ω pull-up resistors at the outputs. However, this configuration is not HDMI-compliant for source devices per specification; it is intended for custom extender designs using Cat5e/Cat6 cabling between chassis.
What is the function of the BYPASS pin on DS22EV5110SQ/NOPB?
The BYPASS pin on DS22EV5110SQ/NOPB disables the retiming and de-emphasis functions when driven HIGH, configuring the device as a pure equalizer. In normal operation (BYPASS = LOW), DS22EV5110SQ/NOPB performs full equalization, CDR-based re-timing, and output de-emphasis.
Does DS22EV5110SQ/NOPB include built-in ESD protection?
Yes, DS22EV5110SQ/NOPB includes >8 kV HBM ESD protection on all pins, as specified in the Absolute Maximum Ratings table of the TI SNLS311E datasheet. This meets industrial handling requirements and reduces need for external TVS diodes in most HDMI interface designs.
