DS90UB936-Q1

Dual FPD-Link III deserializer with CSI-2 replication

Receives up to two FPD-Link III sensor streams and multiplexes them onto CSI-2, with replication for simultaneous capture and processing. The 2×2-lane mode duplicates the same video stream rather than creating two independently routable output ports; replication does not preserve a four-lane interface at each destination.

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. No TI functional-safety category was established in the reviewed product parameters/features. This does not prove that related documents are unavailable; do not infer ASIL or Compliant status.

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

Can replication route a different camera to each of two processors?

Not in replication mode. It repeats the primary CSI output on the second lane group with a duplicate clock. The 2×2 configuration sends two copies of the same stream. Independent source routing to two outputs needs a device supporting that architecture.

Do two 2.528Gbps inputs guarantee 5.056Gbps of images at the host?

No. Per-input bandwidth does not replace checks of CSI output lane count, rate and forwarding schedule. Replication uses at most two data lanes per copy, making overhead and receiver capacity especially important; duplication does not increase unique-image throughput.

How should I verify the DS90UB936-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.
