MC100LVEL34DTR2G

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100LVEL34DTR2G is a low skew clock generation chip designed for ÷2, ÷4, and ÷8 frequency division. It operates in PECL mode with VCC = 3.0 V to 3.8 V (VEE = 0 V) or NECL mode with VCC = 0 V (VEE = −3.0 V to −3.8 V). The device supports a maximum toggle frequency of 1.5 GHz and features synchronous enable/disable and master reset inputs. It provides differential outputs with typical output-to-output skew of 50 ps. The component is housed in a TSSOP-16 package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the device status as discontinued for new designs per the datasheet. Confirm the specific ordering suffix 'DT' corresponds to the TSSOP-16 package and tape & reel shipping method. Ensure compatibility with existing PCB footprints for the 16-lead thin shrink small outline package.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when low skew clock division is required at frequencies up to 1.5 GHz. Ensure the design supports PECL (VCC=3.3V) or NECL (VEE=-3.3V) power supplies. Verify that the TSSOP-16 package dimensions fit the mechanical constraints. Consider the synchronous nature of the enable and reset functions for timing alignment.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the MC100LVEL series, which contains temperature-compensated devices. It is functionally similar to the MC100EL34 but optimized for lower voltage ECLinPS operation. The 'DTR2G' suffix indicates the TSSOP-16 package, tape and reel quantity of 2500 units, and Pb-Free/RoHS compliance.
