Texas Instruments DS22EV5110SQX/NOPB

Overview

DS22EV5110SQX/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, supports 1080p/36-bit color over 25 m of 28 AWG HDMI cable, delivers ≤0.09 UI total output jitter at 2.25 Gbps, and features on-chip 50 Ω CML input termination and open-collector CML outputs for AC/DC-coupled extension applications.

For engineers reviewing the DS22EV5110SQX/NOPB datasheet, DS22EV5110SQX/NOPB pinout, DS22EV5110SQX/NOPB application, or DS22EV5110SQX/NOPB equivalent, key selection criteria include TMDS channel count (4-channel: 3 data + 1 clock), programmable equalization (8 boost levels via EQ[2:0]), de-emphasis control (0/–3/–6/–9 dB), VOD_CRL-configurable output swing (1000 mV_p-p), and WQFN-48 package compatibility with HDMI v1.3a/DVI v1.0 timing budgets.

Technical Context

The DS22EV5110SQX/NOPB implements independent CDR per TMDS data channel with loop bandwidth ≈ bit rate / 1000 (e.g., 2.25 MHz at 2.25 Gbps), fed by a high-performance PLL on the clock channel that regenerates low-jitter sampling clocks. Each CDR digitally interpolates the PLL-derived clock to align sampling edges, enabling deterministic jitter reduction and signal recovery across lossy media.

Input equalization uses an 8-level programmable analog boost stage controlled by EQ2/EQ1/EQ0 pins; output de-emphasis applies four discrete attenuation steps (0/–3/–6/–9 dB) via DE1/DE0 to compensate post-equalizer channel loss. The device supports both DC-coupled (24 kΩ VOD_CRL) and AC-coupled (12 kΩ VOD_CRL + external biasing) configurations for Cat5e/Cat6 or STP HDMI cable extension.

Key Specifications

Pinout & Package

The DS22EV5110SQX/NOPB is housed in a 7 mm × 7 mm, 48-pin WQFN package (RHS0048A) with exposed thermal pad (DAP) requiring connection to ground plane. Pin layout follows standard TMDS I/O grouping: inputs (C_IN±, D_IN0±, D_IN1±, D_IN2±) on left/top edges; outputs (C_OUT±, D_OUT0±, D_OUT1±, D_OUT2±) on right/bottom edges; control (EQ[2:0], DE[1:0], BYPASS, EN, SD, LOCK) and analog (VOD_CRL, LFn, LFp) pins centrally located.

FAQ

What is the maximum supported data rate per channel for the DS22EV5110SQX/NOPB?

The DS22EV5110SQX/NOPB supports up to 2.25 Gbps per TMDS data channel, enabling full HDMI v1.3a compliance including 1080p resolution with 36-bit deep color (6.75 Gbps total). This rate is validated across all operating conditions (0 °C to +70 °C, 3.3 V supply) and confirmed in the SNLS311E datasheet Table "Bit Rate" with bR = 2.25 Gbps max.

How does the DS22EV5110SQX/NOPB handle jitter reduction in HDMI/DVI signals?

The DS22EV5110SQX/NOPB reduces jitter through dual-stage processing: first, a programmable analog equalizer compensates for channel loss-induced deterministic jitter; second, a dedicated CDR per data channel performs clock-data recovery to suppress both deterministic and random jitter. At 2.25 Gbps, total output jitter is specified ≤0.09 UI_p-p, measured at TPC in Figure 1 of the SNLS311E datasheet.

Can the DS22EV5110SQX/NOPB be used with Cat5e/Cat6 unshielded twisted pair cables?

Yes, the DS22EV5110SQX/NOPB supports AC-coupled operation optimized for Cat5e/Cat6 UTP cables. Using a 12 kΩ resistor on VOD_CRL and external 50 Ω pull-ups at outputs + 622 Ω pull-downs at inputs, it extends 1.65 Gbps HDMI signals beyond 30 meters with <0.20 UI jitter - as documented in Table 5 and Application Information section of SNLS311E.

What is the function of the BYPASS pin on the DS22EV5110SQX/NOPB?

The BYPASS pin on the DS22EV5110SQX/NOPB disables retiming and de-emphasis when driven HIGH, configuring the device as a pure analog equalizer. In normal operation (BYPASS = LOW), full CDR-based retiming and output de-emphasis are active. This mode is useful for diagnostic testing or legacy system integration where only equalization is required.

Does the DS22EV5110SQX/NOPB support both DC-coupled and AC-coupled TMDS interfaces?

Yes, the DS22EV5110SQX/NOPB supports both configurations: DC-coupled operation uses a 24 kΩ resistor on VOD_CRL for 1000 mV_p-p swing and direct connection to HDMI sinks; AC-coupled operation uses a 12 kΩ VOD_CRL resistor plus external biasing (50 Ω pull-ups at outputs, 622 Ω pull-downs at inputs) to eliminate ground potential differences - detailed in Figures 9 and 10 of SNLS311E.
