SP8902/KG/MP1T

Overview

The SP8902/KG/MP1T is a high-speed, low-power RF prescaler designed for professional applications. It operates as a divide-by-2 fixed modulus divider with an input frequency range of 1GHz to 5GHz. The device supports operation down to DC with square wave inputs. It is housed in an 8-SOP package and requires a supply voltage typically between 4.75V and 5.25V.

Feature Summary

• High-speed prescaler functionality for professional RF applications
• Low power consumption design optimized for efficiency
• Fixed modulus division ratio of two
• Operational capability from DC up to 5GHz with square wave inputs

Applications

• RF signal processing systems
• Frequency synthesis circuits
• Professional communication equipment

Procurement Notes

Verify the specific suffix MP1T indicates tape and reel packaging when sourcing. Confirm compatibility with 5V logic levels and ensure thermal management meets junction temperature specifications during integration. Cross-reference datasheets for absolute maximum ratings to prevent overvoltage damage.

Selection Notes

Select this component for designs requiring precise frequency division in the 1GHz to 5GHz range. Ensure the application can accommodate the 8-SOP package footprint. Verify that the system architecture supports the required supply voltage stability and that square wave input conditioning is available if operating at lower frequencies.

Part Context

This part belongs to the Zarlink SP890x series of operational amplifiers and prescalers. It is functionally related to variants like the SP8904, sharing similar architectural principles but differing in specific modulus or frequency configurations. The series targets high-performance RF subsystems requiring reliable frequency scaling.

Replacement Considerations

Direct substitutes include other SP8902 variants such as SP8902/KG/MP1S, which differs primarily in packaging format. Ensure pinout compatibility and electrical parameter alignment before substituting with generic equivalents.
