74FCT38072SCMGI

Overview

The 74FCT38072SCMGI is a low skew, single-input to two-output LVCMOS clock buffer manufactured by Renesas Electronics. It features an additive phase jitter of sub-50fs RMS and extremely low output skew of 50ps. The device operates within a supply voltage range of 1.8V to 3.3V and supports input/output clock frequencies up to 200MHz. Packaged in an 8-pin COL (DFN) format with dimensions of 2.0 x 2.0 x 0.5 mm, it utilizes low-power CMOS technology and functions across an extended temperature range of -40°C to +85°C.

Feature Summary

• Low additive phase jitter of sub-50fs RMS
• Extremely low skew outputs at 50ps
• Supports input/output clock frequencies up to 200MHz
• Operates on supply voltages from 1.8V to 3.3V

Applications

• High-speed digital signal processing systems
• Telecommunications equipment requiring precise timing
• Data acquisition systems with strict jitter constraints

Procurement Notes

Verify the specific package suffix 'COL' corresponds to the required 8-pin DFN footprint during procurement. Confirm that the operating environment stays within the specified -40°C to +85°C temperature range. Ensure the design accommodates the 1.8V to 3.3V supply voltage requirements for proper functionality.

Selection Notes

Select this component when sub-50fs jitter performance is critical for system stability. The 1:2 fan-out configuration suits applications needing one source drive two loads. Verify compatibility with LVCMOS logic levels and ensure the PCB layout supports the small 2.0 x 2.0 mm package dimensions.

Part Context

This part belongs to the 74FCT38072 series of clock buffers. It serves as a specialized variant optimized for low jitter and low skew applications compared to standard logic buffers. The COL package provides a compact solution for space-constrained designs requiring high-frequency clock distribution.

Replacement Considerations

Direct replacements include other variants within the 74FCT38072 family such as 74FCT38072SDCGI, provided the SOIC-8 package is acceptable. Cross-reference pinouts and electrical specifications carefully when substituting packages.
