Analog Devices Inc./Maxim Integrated DS34T104GN

DS34T104GN is the four-port member of the DS34T101–DS34T108 circuit-emulation family. It integrates E1/T1/J1 line-interface and framer functions, TDM packetization, clock recovery and a 10/100 Ethernet MAC for carrying synchronous circuits across a packet network.

The manufacturer lists DS34T104GN in a 484-ball thermally enhanced BGA (TEBGA). The existing product and package registry use the broader name 484-BGA. Verify ball map, outline, thermal design and land pattern from the manufacturer's package drawings before PCB release.

Layout checks

• Match the full 484-ball map to the DS34T104 variant.
• Check the TEBGA mechanical outline and thermal guidance.
• Confirm power, ground and high-speed interface routing.

The registered package JPG is not yet available on the production site; the illustration is awaiting upload and visual verification. This draft must not be published while the image returns 404.

The manufacturer data sheet identifies these signal groups for the DS34T104 family; use its ball-assignment tables for exact ball locations.

Signal suffix n denotes a channel index, not a package ball number. Check the exact four-port ball map and electrical tables in Rev. 4; do not infer unused channels from the eight-port variant.

Supply entries describe nominal voltage classes, not absolute maximum or tolerance limits. Consult the manufacturer's recommended-operating and electrical-characteristics tables for numeric design margins.

Other DS34T10x family members differ in port count and possibly ball use or configuration. Compare exact order code, port population, power domains, firmware settings, clock architecture, package drawing and temperature grade before considering a substitution. No unverified LCDChip alternative is linked here; a shared family name is not evidence of drop-in compatibility.

This order code is documented by Analog Devices under the Maxim Integrated DS34T101–DS34T108 data-sheet family. Use the current manufacturer-controlled data sheet, errata and product notices for final component approval.

Confirm the full DS34T104GN marking and traceability documents against the purchase order. Inspect packaging, moisture-sensitive handling and storage conditions before assembly. Electrical acceptance and qualification must follow the manufacturer's current documentation and the buyer's approved process.

This description is a selection aid, not a substitute for the manufacturer's detailed electrical, timing, thermal, pin-assignment and package specifications. Resolve the registered 484-BGA versus manufacturer 484 TEBGA naming at mechanical review, and supply a verified package illustration before making this page public.
