SY55851AUKG

Overview

The SY55851AUKG is a configurable logic gate from the SuperLite family, operating up to 3.0 GHz with propagation delays under 280 ps. It supports supply voltages between 2.3 V and 3.6 V and functions as an AnyGate capable of implementing AND, NAND, OR, NOR, XOR, XNOR, DELAY, or NEGATION logic. The device features fully differential CML outputs optimized for 50 Ω loads and accepts LVPECL or CML inputs. Packaged in a 10-pin MSOP, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Configurable AnyGate architecture supporting multiple Boolean logic functions
• Fully differential CML output stage optimized for 50 Ω termination
• Capable of functioning as a 2:1 multiplexer

Applications

• Port bypass circuits
• Data communication systems
• Wireless communication systems
• Telecom systems

Procurement Notes

Verify that the specific ordering suffix matches the required package type (MSOP) and temperature grade (-40°C to +85°C). Confirm lead finish specifications against project requirements. Ensure input signals are properly terminated externally, as internal terminations are not provided. Validate power supply voltage levels remain within the specified 2.3 V to 3.6 V operational range during system integration.

Selection Notes

Select this component when high-speed configurable logic is required in a compact surface-mount package. It is suitable for designs needing flexible logic implementation without discrete gates. Verify compatibility with LVPECL or CML signal sources. Ensure PCB layout accommodates differential routing for the CML outputs to maintain signal integrity at frequencies approaching 3.0 GHz.

Part Context

This part belongs to Microchip's SuperLite series, designed for high-frequency applications. The SY55851A variant specifically targets 2.5V/3.3V operation with optimized 50 Ω outputs. The 'UKG' suffix denotes the 10-lead MSOP package and industrial temperature range. This series provides universal logic capabilities in a small form factor for dense circuit board layouts.

Replacement Considerations
