SI5330M-B00233-GMR

Clock Buffers, Drivers Overview

The SI5330M-B00233-GMR is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions. It accepts a single-ended input signal and generates four differential HCSL outputs. The device operates with a core supply voltage of 1.8 V (range 1.71–1.98 V) and an independent output driver supply of 1.8 V. Key electrical specifications include a typical propagation delay of 2.5 ns, maximum propagation delay of 4.0 ns, and output-output skew of 100 ps. Additive jitter is typically 150 fs RMS. It functions within an industrial temperature range of –40 to +85 °C and is housed in a 24-lead, 4 x 4 mm QFN package.

Clock Buffers, Drivers Feature Summary

• Converts single-ended input to four differential HCSL outputs
• Typical additive jitter of 150 fs RMS (12 kHz–20 MHz)
• Independent core (VDD) and output (VDDO) supply voltages
• Includes Loss of Signal (LOS) indicator and glitchless Output Enable (OEB)

Clock Buffers, Drivers Applications

• High-speed clock distribution
• Ethernet Switch/Router
• PCI Express 2.0/3.0
• Fibre Channel

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'GMR' indicates tape and reel packaging as per manufacturer documentation. Confirm that the specific B00233 code corresponds to the 1.8 V HCSL configuration. Ensure compatibility with the required 1.8 V output driver supply voltage for the target application circuit.

Clock Buffers, Drivers Selection Notes

Select this part when a single-ended clock source must be distributed to four differential HCSL loads. Verify that the input frequency falls within the 5 to 250 MHz range specified for HCSL outputs. Ensure the system design accommodates the separate 1.8 V supplies for both the core logic and the output drivers.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'M' designation identifies it as the variant supporting single-ended inputs with differential HCSL outputs. The 'B' indicates the output voltage level configuration, while 'R' specifies the reel shipping format.
