M21011G-12

Overview

The MACOM M21011G-12 is a single-circuit clock generator and frequency multiplier designed for high-speed digital applications. It supports CML, LVDS, and LVPECL inputs with LVDS and LVPECL outputs, operating up to 800 MHz. The device features an integrated PLL and a 4:8 input-to-output ratio. It functions on a 1.14V to 1.26V supply voltage within a -40°C to 85°C temperature range. Housed in a 72-VFQFN exposed pad package (10x10 mm), it targets Fiber Channel, Gigabit Ethernet, and SONET systems.

Feature Summary

• Integrated PLL for clock generation and frequency multiplication
• Supports CML, LVDS, and LVPECL input formats
• Provides LVDS and LVPECL differential output options
• Operates at frequencies up to 800 MHz

Applications

• Fiber Channel interfaces
• Gigabit Ethernet systems
• SONET network equipment

Procurement Notes

Verify the specific suffix 'G-12' against official MACOM documentation to confirm pinout compatibility and RoHS status. Ensure the 72-QFN (10x10) package dimensions match the target PCB footprint. Confirm that the 1.14V–1.26V supply requirement aligns with the system power design before procurement.

Selection Notes

Select this component when a single circuit with a 4:8 ratio is required for high-frequency clock distribution. Verify that the system supports the specified CML/LVDS/LVPECL input standards and requires LVDS or LVPECL outputs. Ensure the operating environment stays within the -40°C to 85°C commercial/industrial temperature range.

Part Context

This part belongs to MACOM's Application Specific Clock/Timing category. It is classified as a linear IC featuring an internal phase-locked loop. The device is distinct from general-purpose oscillators by its configurable input/output formats and fixed frequency multiplication capabilities.

Replacement Considerations

No public substitute part numbers are documented. Evaluate alternatives based on matching 800 MHz frequency limits, 72-VFQFN packaging, and compatible CML/LVDS/LVPECL I/O standards.
