SKY53510-A-GMR

Clock Buffers, Drivers Overview

The SKY53510-A-GMR is a high-performance differential clock buffer from Skyworks Solutions, designed for precision clock distribution in systems requiring ultra-low additive jitter. It supports DC to 3.1 GHz operation and features a 3:1 input multiplexer compatible with LVPECL, LVDS, HCSL, CML, SSTL, HSTL, and single-ended clocks. The device includes two independently configurable output banks supporting LVPECL, LVDS, and HCSL formats with selectable voltages of 1.8 V, 2.5 V, or 3.3 V. An integrated LDO provides high PSRR, reducing external component requirements. Additive jitter is typically 35 fs RMS at 156.25 MHz LVPECL.

Clock Buffers, Drivers Feature Summary

• Ultra-low additive RMS jitter: 35 fs typical, 47 fs max at 156.25 MHz LVPECL (12 kHz to 20 MHz)
• 3:1 input multiplexer supporting multiple clock formats including LVPECL, LVDS, HCSL, CML, SSTL, HSTL
• Two output banks with independent format and voltage configuration (LVPECL, LVDS, HCSL, Hi-Z)
• Integrated LDO for high PSRR and reduced external components

Clock Buffers, Drivers Applications

• PCI Express reference clock distribution (Gen1 through Gen7)
• High-speed networking and data center timing architectures
• Industrial and embedded systems requiring low jitter clocks
• Format translation between clock domains
• Synchronization in RF/wireless and instrumentation systems

Clock Buffers, Drivers Part Context

The SKY53510-A-GMR belongs to the SKY53510/SKY53580/SKY53540 series of high-performance differential clock buffers. This family is optimized for applications demanding precise timing and low phase noise, offering compact QFN packaging with options for 4, 8, or 10 differential outputs depending on the specific variant within the series.

Clock Buffers, Drivers Replacement Considerations

Within the same product family, the SKY53510-A-GM is the tape-and-reel equivalent of the SKY53510-A-GMR, differing only in packaging format. Other variants such as SKY53580 and SKY53540 share similar core functionalities but may differ in output count or specific electrical characteristics.
