SI5330H-A00221-GM

Clock Buffers, Drivers Overview

The SI5330H-A00221-GM is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions Inc. It accepts differential input signals and generates eight single-ended outputs in the SSTL format. The device supports a frequency range of 5 to 350 MHz with an additive jitter of 150 fs RMS typical. It operates on a core supply voltage of 1.8, 2.5, or 3.3 V, while the output driver supply is independently set to 2.5 V for SSTL compatibility. Key features include glitchless output enable control via the OEB pin, a Loss of Signal (LOS) indicator, and operation within an industrial temperature range of –40 to +85 °C.

Clock Buffers, Drivers Feature Summary

• Generates eight single-ended SSTL outputs from a differential input
• Additive phase jitter of 150 fs RMS typical (12 kHz–20 MHz)
• Output-output skew of 100 ps maximum
• Glitchless Output Enable (OEB) and Loss of Signal (LOS) monitoring

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• Ethernet Switch/Router systems
• PCI Express 2.0/3.0 interfaces
• Telecom Line Cards

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix A00221 to confirm the 2.5 V SSTL output configuration and differential input requirement. Confirm package type as 24-lead QFN and check for RoHS compliance status. Ensure the procurement source provides valid traceability documentation for this component.

Clock Buffers, Drivers Selection Notes

Select this part when eight single-ended SSTL outputs are required from a differential source. The core supply can be optimized for power consumption at 1.8 V, while the VDDO pins must be supplied with 2.5 V to meet SSTL voltage levels. Verify that the input signal frequency falls within the 5 to 350 MHz range for proper operation.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'H' designation indicates single-ended SSTL outputs with differential inputs. Other variants in the series support LVPECL, LVDS, HCSL, CMOS, and HSTL formats with varying input configurations.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family include SI5330H-A00220-GM (3.3 V SSTL) and SI5330H-A00222-GM (1.8 V SSTL). For different output formats, consider SI5330G-A00217-GM through SI5330G-A00219-GM for CMOS outputs.
