Analog Devices Inc./Maxim Integrated DS3162

The DS3162 maps and demaps ATM cells or HDLC packets between a system-side bus and two independently configurable digital line ports. Each port can be set for supported DS3, E3 or clear-channel operation. On-chip framing and formatting functions reduce the external digital logic required in a telecom interface, while the host configures operating modes and monitors status through the microprocessor interface.

Maxim's exact ordering table specifies 400-ball TE-PBGA, 27 mm × 27 mm, 1.27 mm ball pitch for the unsuffixed DS3162. LCDChip's existing package field is 400-BBGA; its established package register maps that catalog label to 400-BBGA.jpg. The catalog name does not replace the manufacturer's thermal-enhanced package drawing or ball assignment.

Mechanical checks

• Confirm the 27 mm square body, 1.27 mm pitch and A1 orientation.
• Compare all 400 ball assignments with the original board layout.
• Review the central thermal-ground-ball connection and assembly guidance.

The expected catalog JPG is absent locally and returns HTTP 404 on the production site. Restore and visually inspect it before publication.

These are functional groups from the manufacturer documentation, not a replacement for the 400-ball map. The exact port number, multiplexed function and clock mode determine the active signal on many balls.

Consult the complete Rev. 3 data sheet and applicable errata for electrical limits, clocks, interface timing and detailed register behavior.

The DS3161, DS3163 and DS3164 provide one, three and four ports respectively; their family-level pin compatibility does not make them automatically equivalent to a two-port DS3162 in a populated board. Check port wiring, pin multiplexing, bus mode, framing configuration, clocks, register initialization, firmware assumptions and device revision. DS3162N is a different temperature-grade ordering code. Confirm any substitution through board-level tests and manufacturer documentation.

No internal alternative-product link is asserted without an exact LCDChip API catalog match and engineering verification.

Analog Devices hosts the original Maxim Integrated DS3161–DS3164 Rev. 3 data sheet and the DS3162 product page. The document provides exact DS3162 ordering information, dual-port architecture, bus and framing features, 400-ball TE-PBGA drawing and extensive register descriptions. Review the manufacturer's errata for the revision installed in the target system.

Verify the exact DS3162 marking rather than DS3162N or another port-count member. Confirm manufacturer lot traceability, package condition, moisture handling and the target board's installed revision. The absent catalog image does not authenticate the physical part or demonstrate mechanical fit.

Validate external line-interface hardware, DS3/E3 framing, system-bus timing, clocks, register programming, package thermal-ground connections and board assembly against the complete Maxim data sheet and revision-specific errata. Restore and verify the production 400-BBGA JPG before the page is published.
