DS90UB935-Q1

CSI-2-input FPD-Link III sensor serializer

Carries a camera's CSI-2 stream over FPD-Link III while returning control and synchronization over the back channel. Lane configuration is the key input constraint: four-lane operation reduces the per-lane ceiling to 632Mbps, so the two-lane 832Mbps limit cannot be multiplied by four. Serial-link clocking and image overhead need separate budgets.

LifecycleActive

In one sentence: Qualification is grounded in this TI product's documentation; no grade is inferred from temperature. An ordering table may show junction or variant-specific limits, which must be distinguished from ambient conditions. TI explicitly lists Functional Safety-Capable. This is a device-documentation category, not system ASIL certification; assess the exact function, assumptions and safety manual.

Orderable variants (OPNs)

The GPN is for selection; the full OPN is for ordering. These examples were observed on the verification date, not live stock. Variants may differ in package, temperature, gain/threshold and, for PMICs, NVM/sequencing. Distinguish TA from TJ in the exact datasheet.

FAQ

Does the 3Gbps headline guarantee a fixed line rate or image throughput?

No. The forward-transmitter section describes capability up to 4.16Gbps, but the encoded line rate depends on clocking and mode. Neither is the same as the 2.528Gbps combined CSI-2 input limit. Budget the selected clocks, framing overhead and receiver mode instead of using the headline as a rate guarantee.

Can four lanes receive 4 × 832Mbps?

No. 832Mbps per lane applies only to one or two data lanes. Four lanes are limited to 632Mbps each, totaling 2.528Gbps. The sensor output configuration must respect that lower per-lane limit.

How should I verify the DS90UB935-Q1 orderable?

The page lists 2 OPN examples from official material checked on 2026-11-06. Match package, function options and temperature definitions; obtain live price/stock from TI or authorized distributors.
