It integrates input equalisation and output de-emphasis, which compensates for board trace loss and connector reflections without adding a separate retimer or CDR. The 200 ps typical delay keeps lane-to-lane skew within a single bit period at 5 Gbps. The 10 pF input capacitance loads the upstream transmitter less than a discrete equaliser network, preserving signal integrity at the source. ## Supply rail and package constraints for layout The device operates from a 2.375 V to 2.625 V supply — a 2.5 V ±5 % rail. Housed in a 54-WFQFN with exposed pad — the supplier device package is 54-WQFN (10×5.5 mm). Surface-mount only; the 0.50 mm pitch QFN demands a solder-paste stencil with 0.25 mm apertures and a reflow profile matching the lead-free SAC305 alloy. ## Active production and sourcing posture The NOPB suffix confirms lead-free (NiPdAu) finish; no RoHS exemption expiry to track. Sourced per RFQ against your BOM quantity. MOQ is typically a full reel (2500 pcs), but lower quantities can be quoted on request.","metaTitle":"DS50PCI402SQ/NOPB PCIe Gen 2 Redriver 5 Gbps 8-Channel CML","metaDescription":"TI DS50PCI402SQ/NOPB 8-channel PCIe buffer/reDriver, 5 Gbps per lane, CML I/O, input equalization + output de-emphasis, 54-WQFN, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Type":"Buffer, ReDriver","Input":"CML","Output":"CML","Package":"Bulk","Delay Time":"200ps","Applications":"PCIe","Mounting Type":"Surface Mount","Package / Case":"54-WFQFN Exposed Pad","Data Rate (Max)":"5Gbps","lifecycle_stage":"eol_hot","Voltage - Supply":"2.375V ~ 2.625V","Number of Channels":"8","Capacitance - Input":"10 pF","Signal Conditioning":"Input Equalization, Output De-Emphasis","Operating Temperature":"-10°C ~ 85°C","Supplier Device Package":"54-WQFN (10x5.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.11","stockQuantity":0,"priceTiers":[{"qty":43,"price":"$7.11000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f1dfafef7425f6814f04945c0aa473d2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DS50PCI402SQ/NOPB a direct replacement for DS50PCI401?","answer":"The DS50PCI402 is a 5 Gbps, 8-channel device. The DS50PCI401 is a 2.5 Gbps, 4-channel part. They are not pin-compatible — the DS50PCI402 doubles the lane count and data rate.

At 5 Gbps the unit interval is 200 ps, so the delay is exactly one bit period — lane-to-lane skew from the redriver itself is negligible for PCIe Gen 2 timing budgets."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DS50PCI402SQ-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DS50PCI402SQ-NOPB when reusing this data.
