MC10EP139DWG

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC10EP139DWG is a low skew clock generation chip designed for high-speed applications. It features synchronous internal dividers providing ÷2/4 and ÷4/5/6 outputs with precise edge alignment. The device supports PECL (VCC = 3.0 V to 5.5 V, VEE = 0 V) and NECL (VCC = 0 V, VEE = −3.0 V to −5.5 V) modes. Maximum operating frequency exceeds 1.0 GHz. Key electrical parameters include a typical power supply current of 83 mA at 25°C (PECL 3.3 V), propagation delay up to 1000 ps, and output-to-output skew of 50 ps. It operates within a temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Synchronous enable/disable logic prevents runt clock pulses during state changes
• Internal divider synchronization ensures common output edges are precisely aligned
• Integrated VBB pin provides an internally generated reference voltage for single-ended inputs or AC coupling rebiasing
• Master reset input allows system synchronization across multiple chips

Clock Generators, PLLs, Frequency Synthesizers Applications

• Low skew clock generation in high-speed digital systems
• Clock distribution networks requiring synchronized divide-by-2, 4, 5, or 6 outputs
• PECL and NECL compatible circuit interfaces

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'DWG' corresponds to the SOIC-20 Wide Body package with lead-free construction. Confirm RoHS compliance status as indicated in the datasheet. Ensure all VCC and VEE pins are externally connected to power supplies for proper operation. Check moisture sensitivity level requirements for storage and handling.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when precise synchronization between divided clock outputs is required. The device supports both even (÷2, ÷4) and odd (÷5, ÷6) division ratios. Ensure the application voltage matches either PECL or NECL specifications. Consider thermal resistance values if operating near maximum temperature limits.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MC10EP139 belongs to the MC10/100EP series of ECL clock generators. The '10' prefix denotes standard EP devices, while '100' indicates temperature-compensated variants. This specific part number uses the DWG suffix for a 20-lead SOIC wide body package.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

MC10EP139DTG is a direct functional substitute using a TSSOP-20 package. MC100EP139DWG offers temperature compensation but shares the same pinout and functionality.
