MC100LVEP34DTR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100LVEP34DTR2G is a low skew clock generation chip from onsemi's 100 Series, designed for precise timing applications. It provides ÷2, ÷4, and ÷8 division ratios with internally synchronous dividers to ensure aligned output edges. The device supports PECL (VCC = 2.375 V to 3.8 V) and NECL (VEE = −2.375 V to −3.8 V) modes, accepting LVDS, CML, NECL, or PECL inputs. Key electrical parameters include a maximum toggle frequency of 2.8 GHz, 35 ps output-to-output skew, and an RMS jitter of 0.36 ps at 2.5 GHz for the ÷2 output. It operates within a temperature range of −40°C to +85°C and is housed in a 16-lead TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Low Skew Design: Achieves 35 ps output-to-output skew with synchronous internal dividers for precisely aligned common output edges.
• Flexible Input/Output: Accepts differential LVDS, CML, NECL, or PECL inputs and provides differential ECL outputs.
• Synchronous Control: Features synchronous enable/disable and master reset functions to prevent runt pulses and ensure system synchronization.
• Integrated Reference Voltage: Includes a VBB pin providing an internally generated reference voltage for single-ended input biasing.

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 that the ordering suffix 'R2G' corresponds to the Tape & Reel packaging format as specified in the datasheet. Confirm RoHS compliance status, noting that while the datasheet lists the devices as Pb-Free and Halogen Free, specific lot markings should be checked against current manufacturer declarations. Ensure the supply chain source provides valid traceability documentation for the component.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when sub-nanosecond skew between multiple clock phases is critical. It is suitable for designs requiring ÷2, ÷4, or ÷8 division without external logic. Verify that the input signal swing meets the minimum 150 mV requirement for guaranteed AC performance. Ensure the power supply configuration matches either PECL (+2.375 V to 3.8 V) or NECL (−2.375 V to −3.8 V) standards.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC100LVEP34 series, which includes variants such as MC100LVEP34DG (SOIC-16) and MC100LVEP34DTG (TSSOP-16 tube). The DTR2G suffix specifically denotes the TSSOP-16 package supplied in a tape and reel format for automated surface-mount assembly. It is part of onsemi's temperature-compensated 100 Series ECL family.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same series include MC100LVEP34DTG (tube version) and MC100LVEP34DG (SOIC package). Cross-family substitution requires verification of voltage levels and pinout compatibility.
