What are the key features of DS22EV5110SQ?
- High-speed signal equalization restores multi-gigabit serial data integrity lost to PCB trace and cable attenuation at up to 3.465 V supply
- 48-pin very-thin chip-carrier (S-XQCC-N48) package with integrated heat slug supports dense backplane and line-card layouts requiring thermal management
- Single-function equalizer architecture simplifies implementation in serial data links by providing dedicated channel compensation without external DSP resources
What is DS22EV5110SQ used for?
The DS22EV5110SQ is used in backplane data links and cable interconnects where high-speed serial signals experience frequency-dependent attenuation that degrades bit error rates at multi-gigabit rates. It suits 10G Ethernet, InfiniBand, and proprietary high-speed bus architectures in server line cards and storage switches where compact 48-pin packaging and integrated heat-slug cooling are required. Signal conditioning stages in test equipment and communications line cards also employ this equalizer to extend reach without increasing transmit power.

Frequently Asked Questions
What supply voltage does DS22EV5110SQ require, and how does it affect board power rail design?
The DS22EV5110SQ operates from a maximum supply voltage of 3.465 V, which aligns with a standard 3.3 V power rail plus a 5% tolerance margin. Board designers can power it directly from the same 3.3 V rail used by other digital logic components, simplifying power architecture by avoiding an additional voltage domain for the equalizer function.
For a multi-gigabit backplane with 30 dB trace loss at Nyquist, can DS22EV5110SQ recover the signal?
High-speed equalizer ICs in the DS22EV5110 family are designed to compensate for significant insertion loss in FR4 backplane traces and cables at multi-gigabit rates, with channel loss correction capability spanning several decibels at Nyquist frequency. The 48-pin chip-carrier package accommodates the necessary analog front-end circuitry and power dissipation to handle substantial equalization tasks, though the exact maximum loss budget should be verified against the device datasheet for the specific data rate and channel length.
When does the DS22EV5110SQ 48-pin chip-carrier package offer a thermal advantage over smaller QFN packages for equalizer applications?
The DS22EV5110SQ's 48-pin chip-carrier format includes an integrated heat slug that conducts heat from the die to the PCB ground plane, reducing junction-to-board thermal resistance by several degrees per watt compared to standard QFN packages without exposed pads. In high-density line cards where multiple equalizer channels operate simultaneously at 3.3 V, this thermal advantage prevents localized hot spots and maintains signal integrity by keeping the analog equalizer circuitry within its specified operating temperature range.
