SKY74038-13

Overview

The SKY74038-13 is a dual-channel fractional-N and integer-N frequency synthesizer designed for wireless communication systems. It integrates two independent synthesizers operating at 2.6 GHz and 800 MHz, supporting GSM applications. The device utilizes a TSSOP-28 package with dimensions of 6.5 x 4.4 mm and a height of 1 mm. It functions as an RF misc IC module, providing precise frequency generation capabilities required for mobile phone baseband processors.

Feature Summary

• Dual-channel architecture supporting simultaneous 2.6 GHz and 800 MHz operation
• Supports both fractional-N and integer-N synthesis modes for flexible frequency planning
• Integrated design suitable for GSM standard compliance

Applications

• GSM mobile phone baseband systems
• Wireless communication frequency generation
• RF transceiver local oscillator sources

Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm RoHS3 compliance requirements against current environmental regulations. Ensure the TSSOP-28 package compatibility with existing PCB footprints. Validate that the 2.6 GHz and 800 MHz dual-channel configuration meets specific system bandwidth needs. Check for available substitute components due to lifecycle status.

Selection Notes

Select this component only if dual-frequency synthesis at 2.6 GHz and 800 MHz is strictly required. The TSSOP-28 package size must fit the mechanical constraints of the target design. Verify that the GSM application profile aligns with the device's operational specifications. Consider the obsolete lifecycle status when designing for long-term production runs.
