DP83TG720S-Q1

1 Gbps single-pair automotive Ethernet PHY

Implements the IEEE 802.3bp / 1000BASE-T1 physical layer for a matching host MAC, not an Ethernet switch. Even where layout reuse is possible, compare MAC interface, BOM, harness and software initialization across data rates.

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

Is this a switch with a MAC?

No. This is a single-port PHY. Data-link control and switching/routing belong to the host or other devices.

Are 100M and gigabit parts direct substitutes?

No guarantee. TI's board-reuse statements have BOM/interface conditions. Verify link-partner rate, clocks, software and EMC, without assuming dual-rate fallback.

How should I verify the DP83TG720S-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.
