224G ICs optimize signal integrity in linear optics
Semtech’s 224-Gbps/lane TIAs and drivers power 800G–3.2T transceivers and optical engines for AI/ML clusters, hyperscale data centers, and cloud infrastructure. Compliant with CEI‑224G‑Linear and LPO‑MSA, they support half-retimed (LRO), linear pluggable (LPO), next‑gen (XPO), near‑packaged (NPO), and co‑packaged (CPO) optics.
The 224G TIA family—GN1834L, GN1834DL, and GN1838DL—offers quad- and octal-channel architectures with flexible layouts. On-chip equalization, high linearity, and low noise boost signal integrity for LPO and next-generation linear optics.
The 224G Mach-Zehnder Modulator (MZM) drivers—quad GN1877 and octal GN1887—support SiPho, InP MZM, and TFLN optical transmitters with tunable gain and output swing. A CEI‑224G‑Linear host-side equalizer covers a wide range of host interfaces, from compact NPO/CPO to varied LRO/LPO/XPO trace lengths.
Both the TIA and driver series integrate real-time link monitoring and telemetry, enabling proactive diagnostics to reduce link flapping and improve network reliability.
The GN1834L, GN1834DL, and GN1887 are available now; GN1838DL and GN1877 are expected in April 2026.
