Overview
The SY55853UKI is a single-bit D-type transparent latch from the SuperLite family, manufactured by Microchip Technology. It operates on a 2.3V to 5.7V power supply and supports a maximum frequency of 2.5GHz. The device features fully differential source-terminated CML outputs and accepts CML, PECL, or LVPECL input logic levels. It includes an asynchronous level-sensitive reset and is housed in a 10-pin MSOP package with an industrial operating temperature range of -40°C to +85°C.
Feature Summary
- Fully differential architecture with source-terminated CML outputs for fast edge rates
- Asynchronous level-sensitive reset functionality
- Compatible with CML, PECL, and LVPECL input logic levels
Applications
- High-speed logic circuits
- OC-48 communication systems
Procurement Notes
Verify the specific ordering suffix to confirm the package type, lead finish, and operating temperature range. The UKI suffix indicates an industrial temperature grade and standard Sn-Pb lead finish. Confirm availability as this component may be subject to lifecycle changes. Ensure compatibility with existing system voltage requirements before procurement.
Selection Notes
Select this component when a high-speed single-bit latch with differential signaling is required. It is suitable for designs needing CML interface compatibility and low propagation delay. Consider the 10-pin MSOP package size for space-constrained layouts. Verify that the system can support the specified power supply range and termination schemes for optimal signal integrity.
Part Context
This part belongs to the SuperLite family of high-speed CML logic devices. The family is characterized by small packaging options and wide supply voltage operation. The SY55853U variant specifically provides a transparent latch function with differential inputs and outputs, designed for integration into high-frequency digital systems requiring precise timing control.
Replacement Considerations
Check for SY55853UKG if a Pb-free NiPdAu lead finish is required for new designs. Other variants like SY55853UKC are available for commercial temperature ranges.
