SKY53510-A-GM

Clock Buffers, Drivers Overview

The SKY53510-A-GM is a low-power, ultra-low additive jitter differential clock buffer from Skyworks Solutions. It operates up to 3.1 GHz and features a 3:1 input multiplexer supporting universal formats including LVPECL, LVDS, HCSL, CML, SSTL, HSTL, and crystal inputs. The device provides 10 differential outputs across two banks, each independently configurable for LVPECL, LVDS, or HCSL signal formats with selectable supply voltages of 1.8 V, 2.5 V, or 3.3 V. It includes an integrated LDO for high PSRR and an LVCMOS reference output.

Clock Buffers, Drivers Feature Summary

• Ultra-low additive RMS phase jitter: 35 fs typical (12 kHz to 20 MHz) at 156.25 MHz LVPECL
• 3:1 input multiplexer accepting LVPECL, LVDS, S-LVDS, HCSL, CML, SSTL, HSTL, sine wave, and crystal inputs
• 10 differential outputs in two independent banks with pin-selectable formats (LVPECL, LVDS, HCSL)
• Integrated LDOs provide high power supply rejection ratio (PSRR) and reduce external component count

Clock Buffers, Drivers Applications

• PCI Express Gen1 through Gen7 reference clock distribution
• High-speed networking and data center timing architectures
• Industrial and embedded systems requiring precise low-jitter clocks
• Format translation between different clock domains

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'A' against the official datasheet to confirm package type and temperature range. Confirm RoHS compliance status via the manufacturer's Certificate of Conformance. Ensure the ordering part number matches the required output configuration and voltage specifications.

Clock Buffers, Drivers Selection Notes

Select this model for applications requiring differential outputs up to 3.1 GHz with ultra-low jitter performance. Compare with SKY53580 (8 outputs) or SKY53540 (4 outputs) if fewer channels are needed. Ensure the input clock format matches the supported universal inputs and verify that the required output voltage levels (1.8 V, 2.5 V, or 3.3 V) align with the system design.

Clock Buffers, Drivers Part Context

This component belongs to the SKY535x0/x1 family of fanout buffers designed for high-frequency, low-jitter clock distribution. The 'SKY53510' designation specifically indicates the variant with 10 differential outputs housed in a 48-pin QFN package. It is optimized for complex timing architectures in high-speed digital systems.

Clock Buffers, Drivers Replacement Considerations

Direct functional substitutes within the same family include SKY53580-A-GM (8 outputs) and SKY53540-A-GM (4 outputs). For LVCMOS-only requirements, consider the SKY53511-A-GM variant. Verify pin compatibility and output count before substitution.
