DS3150QN+

Telecom Overview

The DS3150QN+ is a Line Interface Unit (LIU) designed for physical layer interfacing to DS3, E3, and STS-1 lines. It integrates transmitter, receiver, and jitter attenuator functions within a single component. The device operates on a 3.3V supply with 5V tolerant I/O and supports an industrial temperature range from -40°C to +85°C. It utilizes a 28-pin PLCC package. The data rate is 51.840 Mb/s for STS-1 applications, with the unit supporting one channel. Maximum power supply voltage is 3.465 V, while the minimum is 3.135 V.

Telecom Feature Summary

• Includes loss-of-signal detection compliant with ANSI T1.231 and ITU-T G.775 standards

Telecom Applications

• SONET/SDH and PDH Multiplexers
• Digital Cross-Connects
• Access Concentrators
• ATM and Frame Relay Equipment
• Routers and PBXs

Telecom Procurement Notes

Verify the specific ordering suffix (+) indicates RoHS compliance when sourcing this component. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the package type matches the required 28-pin PLCC configuration for your design. Check current availability status as distribution channels may vary.

Telecom Selection Notes

Select the DS3150QN+ for designs requiring a drop-in replacement for legacy TDK components like the 78P2241/B or 78P7200L. Verify that the application requires support for bipolar and NRZ interfaces. Ensure the system can accommodate the necessary external transformers and capacitors shown in the datasheet diagrams for proper signal integrity.

Telecom Part Context

This component belongs to the DS3150 family of telecom interface ICs. Other variants include the DS3150Q for commercial temperature ranges and the DS3150T series in 48-pin TQFP packages. The DS3150QN+ specifically denotes the industrial temperature grade version housed in a plastic leaded chip carrier package.

Telecom Replacement Considerations

The datasheet identifies the TDK 78P2241/B and 78P7200L as direct drop-in replacements. The DS3150Q is pin-compatible with the TDK 78P7200.
