SI5330A-A00202-GM

Clock Buffers, Drivers Overview

The Si5330A-A00202-GM is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions Inc. It accepts a differential input signal and generates four differential LVPECL outputs at 2.5 V. The device supports a frequency range of 5 to 710 MHz with an additive jitter of 150 fs RMS typical. It operates on a single core supply (1.8, 2.5, or 3.3 V) with independent output driver supplies. 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 in a 24-lead QFN package.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm configuration details. Confirm that the component meets RoHS compliance standards as specified in the datasheet. Check for any Product Change Notifications (PCNs) regarding lead frame modifications or moisture sensitivity ratings prior to procurement.

Clock Buffers, Drivers Selection Notes

Select this part when a differential-to-differential translation to 2.5 V LVPECL is required. Ensure the system design accommodates separate core (VDD) and output (VDDO) supply voltages. Verify that the input clock signal characteristics fall within the specified differential voltage swing and rise/fall time limits for optimal performance.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of clock buffers. The 'A' designation indicates a differential input configuration. The '00202' code specifies the generation of four differential LVPECL outputs operating at a 2.5 V logic level. This distinguishes it from other variants offering different output formats like LVDS, HCSL, or CMOS.

Clock Buffers, Drivers Replacement Considerations

Si5330A-A00200-GM provides identical functionality but with 3.3 V LVPECL outputs instead of 2.5 V.

Clock Buffers, Drivers FAQ

What is the function of the LOS pin?

The LOS pin is an open-drain output that indicates the status of the input clock. It asserts low when a valid clock signal is present and goes high when a loss of signal is detected.

How does the OEB pin operate?

The Output Enable (OEB) pin allows glitchless control of the output clocks. Connecting it to ground enables all outputs, while connecting it to VDD disables them, forcing outputs to a logic low state.

Can the core supply voltage differ from the output supply voltage?

Yes, the Si5330 features independent core (VDD) and output driver (VDDO) supplies. The core can operate at 1.8, 2.5, or 3.3 V, while the output supply must match the required output signal format voltage.
