What are the key features of DS25CP152QSQ?
- Dual-channel CML repeater operating at data rates up to 1.5 Gbps for SATA and SAS signal restoration
- Integrated pre-emphasis and equalization compensating up to 20 dB of trace loss at 750 MHz
- 2.5 V to 3.3 V supply voltage range ensuring compatibility with modern multi-rail board designs
- QFN package minimizes parasitic inductance, supporting clean eye diagrams in dense backplane layouts
What is DS25CP152QSQ used for?
DS25CP152QSQ is used in SATA and SAS storage systems to restore signal integrity across long PCB traces or connector interfaces operating at 1.5 Gbps. It is well suited for server backplanes, RAID controllers, and network attached storage (NAS) designs where two high-speed serial channels need simultaneous conditioning. The device also serves in test equipment and industrial communication cards that require reliable CML-level signal repeating with minimal added jitter.

Frequently Asked Questions
What maximum data rate does DS25CP152QSQ support, and which serial protocols does it target?
DS25CP152QSQ supports data rates up to 1.5 Gbps per channel, making it directly compatible with SATA Gen 1 and SAS interfaces. Both of its 2 independent CML channels can operate simultaneously at this rate, allowing a single IC to condition two serial links in a storage controller or backplane design without external signal boosters.
How much PCB trace loss can DS25CP152QSQ compensate, and what does that mean for board design?
The device integrates equalization capable of compensating approximately 20 dB of insertion loss at 750 MHz, which corresponds to roughly 20 to 30 inches of standard FR4 trace. This level of equalization lets designers route SATA or SAS traces across full ATX motherboard lengths or through multiple connectors while maintaining open, compliant eye diagrams at 1.5 Gbps.
What supply voltage range does DS25CP152QSQ accept, and how does that affect system power planning?
DS25CP152QSQ accepts a 2.5 V to 3.3 V supply, giving designers flexibility to power it from either a 3.3 V system rail or a dedicated 2.5 V rail in power-optimized platforms. At 2.5 V operation the device draws reduced quiescent current, helping lower total board power in dense server blades with many storage channels.
When should DS25CP152QSQ be chosen over a passive equalizer for SATA signal conditioning?
DS25CP152QSQ is preferred over a passive equalizer when trace loss exceeds 10 dB at 750 MHz or when the channel includes multiple connectors and vias that a passive RC network cannot fully compensate. The active repeater restores both amplitude and jitter margin, ensuring the 1.5 Gbps signal meets SATA Gen 1 receiver sensitivity specifications even on worst-case long routing paths of 25 inches or more.
