Product details
Overview
DS22EV5110SQE/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, delivers 0.09 UI total output jitter at 2.25 Gbps, supports 25 m of 28 AWG HDMI cable for 1080p/36-bit color, and operates from 3.3 V over 0 °C to +70 °C in a 7 mm × 7 mm 48-pin WQFN package.
For engineers reviewing the DS22EV5110SQE/NOPB datasheet, DS22EV5110SQE/NOPB pinout, DS22EV5110SQE/NOPB application, or DS22EV5110SQE/NOPB equivalent, this device is selected for HDMI/DVI source, sink, and repeater designs requiring deterministic jitter reduction, programmable equalization (0–30 dB), and de-emphasis tuning (0 to –9 dB) in high-speed video signal conditioning systems.
Technical Context
The DS22EV5110SQE/NOPB implements independent CDR units per TMDS data channel, each locked to a high-performance PLL on the clock channel; loop bandwidth scales as baud_rate/1000 (e.g., ~2.25 MHz at 2.25 Gbps). Input equalization uses eight programmable boost levels (0–30 dB) via EQ[2:0] pins to compensate path loss across STP or UTP cables.
Output drivers support resistor-adjustable differential voltage (800–1200 mVp-p) and four de-emphasis settings (0, –3, –6, –9 dB) via DE[1:0]; all CML I/Os feature on-chip 50 Ω termination (inputs pulled to VDD) and open-collector outputs (outputs). Signal Detect (SD) and LOCK indicators provide real-time channel status for system-level fault management.

Applications
| HDMI/DVI Source Extension | HDMI/DVI Repeater Box |
|---|---|
|
Use Scenario: Extending HDMI output from graphics cards or Blu-ray players beyond native cable limits using active equalization. IC Role / Device Role / Timing Role: DS22EV5110SQE/NOPB acts as a source-side reconditioning IC, applying de-emphasis to drive 25 m of 28 AWG HDMI cable while maintaining eye opening. Use Value: Enables 1080p/36-bit color transmission over 25 m without signal degradation, eliminating need for active optical or powered repeaters. |
Use Scenario: Building compact HDMI extender boxes that accept input from a source and retransmit clean signal to a display over longer distances. IC Role / Device Role / Timing Role: DS22EV5110SQE/NOPB serves as a full repeater-equalizing incoming degraded signal, retiming with CDR, then de-emphasizing output for downstream cable drive. Use Value: Achieves end-to-end jitter reduction (0.09 UI) and supports dual-cable configurations (e.g., 7.5 m + 25 m) with no external clock reference required. |
| HDMI/DVI Sink Conditioning | AV Distribution over Cat6 |
|
Use Scenario: Integrating into high-definition displays or projectors to recover weak or distorted HDMI signals from long cable runs. IC Role / Device Role / Timing Role: DS22EV5110SQE/NOPB functions as a sink-side equalizer, restoring signal integrity before HDMI receiver logic, with EQ tuned to cable loss. Use Value: Recovers usable eye diagrams from signals attenuated by >25 m of 28 AWG HDMI, enabling reliable display operation without redesigning front-end analog circuitry. |
Use Scenario: Transmitting HDMI video over low-cost Cat5e/Cat6 UTP cabling in digital signage or broadcast infrastructure. IC Role / Device Role / Timing Role: DS22EV5110SQE/NOPB conditions TMDS signals for AC-coupled UTP transport, using 12 kΩ VOD_CRL and 622 Ω input biasing per TI AN-1187 guidelines. Use Value: Supports >30 m reach at 1.65 Gbps with <0.20 UI jitter on low-skew Cat6, reducing installation cost versus shielded HDMI cable. |
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 |
|---|---|---|---|
| SN65DP159RSBT | PCIe 3.0 retimer architecture; supports DisplayPort 1.2a and HDMI 2.0 via protocol translation; higher power (1.8 W) | Targets DP-to-HDMI bridges and multi-standard docking stations; not pin-compatible; requires different layout and firmware | Select SN65DP159RSBT when supporting DisplayPort sources or needing HDMI 2.0 bandwidth (6 Gbps per lane); DS22EV5110SQE/NOPB remains optimal for pure DVI/HDMI v1.3a extension. |
| PTN3362BS/F | Single-lane HDMI 1.4b redriver; no CDR or equalization; fixed 6 dB de-emphasis; 48-pin TQFP package | Limited to short-reach (<10 m) boosting; lacks jitter cleanup or adaptive EQ; lower BOM cost but no repeater capability | Choose PTN3362BS/F for cost-sensitive HDMI source buffering where cable length ≤10 m and jitter budget permits; DS22EV5110SQE/NOPB is required for >15 m or repeater use cases. |
Compared with SN65DP159RSBT and PTN3362BS/F, DS22EV5110SQE/NOPB uniquely combines full CDR-based retiming, wide-range programmable equalization (0–30 dB), and multi-level de-emphasis in a single HDMI/DVI-optimized IC-making it the only choice for robust 25 m extension and true repeater functionality without protocol translation overhead.

FAQ
What is the maximum supported cable length for DS22EV5110SQE/NOPB at 2.25 Gbps?
The DS22EV5110SQE/NOPB equalizes greater than 25 meters of 28 AWG HDMI cable at 2.25 Gbps for 1080p/36-bit color, as verified in TI's SNLS311E datasheet Figure 13–17. Performance depends on cable quality and EQ setting; Table 4 recommends EQ = 0x06 for >10 m STP cables at this rate. Longer reach is possible with low-skew Cat6 UTP using EQ = 0x05.
Does DS22EV5110SQE/NOPB require an external clock source?
No, DS22EV5110SQE/NOPB does not require an external clock source. Its internal high-performance PLL locks to the incoming TMDS clock channel and regenerates a low-jitter sampling clock for all CDR units. External loop filter components (2.2 nF capacitor and 3.3 kΩ resistor between LFn and LFp) are required, but no crystal or oscillator is needed.
How is output differential voltage (VO) configured on DS22EV5110SQE/NOPB?
DS22EV5110SQE/NOPB sets output differential voltage via the VOD_CRL pin: connect 24 kΩ to GND for DC-coupled applications (1000 mVp-p), or 12 kΩ to GND for AC-coupled setups (also 1000 mVp-p). Resistor tolerance should be ±5%; values outside 12–24 kΩ are not supported per TI SNLS311E Section 8.3.
Can DS22EV5110SQE/NOPB operate in equalizer-only mode without retiming?
Yes, DS22EV5110SQE/NOPB can operate in equalizer-only mode by asserting HIGH on the BYPASS pin. In this state, the CDR and de-emphasis blocks are disabled, and the device passes equalized signals with minimal latency. The LOCK and SD pins remain functional, allowing system monitoring even in bypass mode.
What is the power consumption of DS22EV5110SQE/NOPB under typical operation?
DS22EV5110SQE/NOPB consumes 1000–1150 mW when enabled (EN = HIGH) with PRBS15 pattern at 225 MHz, and 750–900 mW in standby mode (EN = LOW), per Electrical Characteristics table in SNLS311E. Power is supplied via six VDD pins (3.3 V ±5%), each requiring a 0.1 µF bypass capacitor placed close to the package.
