MC100LVEL34DTG

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100LVEL34DTG is a low skew clock generation chip from onsemi's 100LVEL series, housed in a TSSOP-16 package. It provides synchronous divide-by-2, divide-by-4, and divide-by-8 outputs with a maximum toggle frequency of 1.5 GHz. The device supports PECL mode (VCC = 3.0 V to 3.8 V) and NECL mode (VEE = -3.0 V to -3.8 V). Key electrical characteristics include a typical output-to-output skew of 50 ps and cycle-to-cycle jitter under 1 ps. It features a dedicated VBB pin for internal reference voltage generation and single-ended input compatibility.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Clock Generators, PLLs, Frequency Synthesizers Applications

• Low skew clock distribution networks
• High-speed data acquisition systems
• Telecommunications infrastructure requiring precise timing alignment

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the DT suffix indicates the TSSOP-16 package configuration. Confirm RoHS compliance status as the datasheet lists the device as Pb-Free and Halogen Free. Check current availability as the SOIC-16 variant is marked discontinued, though the TSSOP version remains active.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when sub-nanosecond skew between multiple clock dividers is required. Ensure the design accommodates the specific power supply requirements for either PECL (+3.3V) or NECL (-3.3V) operation. Verify that the 1.5 GHz maximum toggle frequency meets the system clock speed requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC100LVEL34 series, which includes variants in SOIC-16 and TSSOP-16 packages. The DTG suffix specifically denotes the TSSOP-16 package with lead-free construction. Other series members may offer different packaging or slight parameter variations but share the core clock generation functionality.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include MC100LVEL34DR2G (SOIC-16, discontinued) and MC100LVEL34DTR2G (TSSOP-16 Tape & Reel). Cross-package substitution requires verifying pinout compatibility and thermal management differences between SOIC and TSSOP footprints.
