M21605G-12

Overview

The M21605G-12 is a 160x160 asynchronous crosspoint switch IC manufactured by MACOM Technology Solutions. It supports high-speed data switching with individual lanes operating at data rates up to 12.5 Gbps. The device features programmable input equalization capable of compensating for up to 27 dB of loss and output drivers with up to 12 dB of post-tap and 5 dB of pre-tap deemphasis. It operates from a single 1.8 V supply, offers low latency of less than 2 ns, and includes four integrated temperature sensors with programmable alarms.

Feature Summary

• Non-blocking 160x160 crosspoint array architecture
• Programmable input equalization and output deemphasis
• Integrated temperature sensing with alarm capabilities
• Flexible configuration via serial or parallel interfaces

Applications

• Backplane switching and signal conditioning
• Datacom and telecom enterprise switchers/routers
• DWDM switches
• Serial Digital Video (SDI) switchers/routers
• Storage Area Network (SAN) switch fabrics

Procurement Notes

Verify the specific package type and voltage requirements against the official datasheet before procurement. Confirm interface compatibility with the host system's control logic. Ensure thermal management solutions align with the device's power dissipation characteristics. Validate that the supply voltage matches the specified 1.8 V core requirement.

Selection Notes

Select this component for applications requiring high-density, non-blocking switching in datacom or telecom environments. Consider its programmable equalization for long-reach backplane applications. Evaluate the flexible configuration options to ensure seamless integration with existing control systems. Verify support for required data rates up to 12.5 Gbps.

Part Context

The M21605G-12 belongs to the M21605 family of high-performance asynchronous fully nonblocking crosspoint switches. This family includes variants such as the M21601 and M21080, which offer different matrix sizes like 120x120 and 80x80 respectively. These devices are designed for multi-rate routing and switching within a single device.

Replacement Considerations

The M21605G-11P is listed as a related part number for the same 160x160 crosspoint switch category. Verify pinout and electrical specifications before substitution.
