Overview
The SI5340A-B03284-GMR is a programmable clock generator from the Si5340 series by Skyworks Solutions. It features four outputs capable of generating any frequency below 1.028 GHz with ultra-low jitter performance specified at 90 fs. The device operates within a supply voltage range of 1.71 V to 3.47 V and supports multiple output types including CML, HCSL, LVCMOS, LVDS, and LVPECL. It is housed in a QFN-44 package and functions within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Ultra-low jitter specification of 90 fs
- Four independent outputs supporting frequencies up to 1.028 GHz
- Flexible output interface options: CML, HCSL, LVCMOS, LVDS, LVPECL
- MultiSynth technology for precise clock generation
Applications
- High-speed data communication systems
- Telecommunications infrastructure equipment
- Test and measurement instruments requiring precise timing
Procurement Notes
Verify the specific suffix 'GMR' indicates tape-and-reel packaging versus 'GM' tray packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement.
Selection Notes
Select this component for designs requiring low-jitter clock synthesis with mixed-signal output compatibility. Ensure the input frequency does not exceed 750 MHz. Validate power consumption requirements against the typical operating current of 115 mA to 120 mA.
Part Context
This part belongs to the Si5340 family of ultra-low-jitter clock generators. It shares core architecture with variants like SI5340A-D-GM but differs in pre-programmed configuration and packaging format. The B03284 suffix denotes a specific factory-programmed frequency plan.
Replacement Considerations
Direct functional replacements include other Si5340A variants such as SI5340A-D-GM, provided the pinout and electrical specifications match the design requirements. Verify that alternative parts support the required output voltage levels and jitter performance.
