ICS853111AYLF

Clock Buffers, Drivers Overview

The ICS853111AYLF is a low skew, high performance 1-to-10 Differential-to-LVPECL/ECL Fanout Buffer from the HiPerClockS family. It features ten differential LVPECL outputs and two selectable differential clock inputs (PCLK/nPCLK) that accept LVPECL, LVDS, CML, or SSTL levels. The device operates with VCC supplies ranging from 2.375V to 5.25V (VEE = 0V) for LVPECL mode, or VEE supplies from -5.25V to -2.375V (VCC = 0V) for ECL mode. Key electrical parameters include a maximum output frequency exceeding 3GHz, typical output skew of 23ps, part-to-part skew of 85ps, propagation delay of 705ps, and additive phase jitter under 0.3ps RMS. It functions within an ambient temperature range of -40°C to 85°C.

Clock Buffers, Drivers Procurement Notes

Verify the RoHS 6 compliant status indicated by the 'LF' suffix against current manufacturer specifications. Confirm the package type corresponds to the 32-lead LQFP (Y suffix) with dimensions 7mm x 7mm x 1.4mm. Ensure the operating temperature grade covers the required -40°C to 85°C range for the specific application environment.

Clock Buffers, Drivers Selection Notes

Select this component when a 1-to-10 fanout buffer is required with input compatibility for multiple differential standards including LVDS and CML. Choose based on the need for sub-nanosecond propagation delay and minimal additive jitter below 0.3ps RMS. Verify that the system power supply architecture supports either positive voltage LVPECL operation or negative voltage ECL operation.

Clock Buffers, Drivers Part Context

The ICS853111A belongs to the HiPerClockS family of high-performance clock solutions originally developed by Integrated Device Technology (IDT). This series is designed for applications requiring well-defined performance and repeatability in clock distribution. The device serves as a buffer to translate various differential input signals into standardized LVPECL or ECL levels for downstream logic.

Clock Buffers, Drivers Replacement Considerations

The datasheet notes pin compatibility with MC100EP111 and MC100LVEP111. Verify functional equivalence and electrical parameter alignment before substitution.
