SI53358A-D01AM

Clock Buffers, Drivers Overview

The SI53358A-D01AM is an automotive-grade, universal clock buffer featuring eight outputs and two inputs. It operates within a frequency range of 10 MHz to 250 MHz and supports both differential and single-ended output formats. The device includes built-in low-dropout regulators (LDOs) for high power supply noise rejection and offers typical additive phase jitter of 120 fs RMS at 156.25 MHz. It is AEC-Q100 qualified for operation across temperatures from -40 °C to +105 °C.

Clock Buffers, Drivers Feature Summary

• Eight outputs with optional dual input capability via hardware-controlled MUX
• Pin-selectable output formats including LVPECL, LVDS, HCSL, and LVCMOS
• Typical 120 fs RMS additive phase jitter performance
• Built-in LDOs providing high PSNR and simplified design

Clock Buffers, Drivers Applications

• Automotive infotainment systems
• Advanced Driver Assistance Systems (ADAS)
• Radar sensors
• Automated driving processing units

Clock Buffers, Drivers Procurement Notes

Verify the specific package type and temperature rating against project requirements. Confirm that the pin-selectable configuration aligns with the hardware control pins available on the target PCB layout. Ensure compatibility with the required output voltage levels before procurement.

Clock Buffers, Drivers Selection Notes

Select this part when eight buffered clock signals are required in an automotive environment. Verify that the desired output format (LVPECL, LVDS, HCSL, or LVCMOS) can be configured using the Format_SEL pins. Check if the 10-250 MHz operating range meets the system's frequency needs.

Clock Buffers, Drivers Part Context

This component belongs to the Si5335x family of universal clock buffers. It shares architectural similarities with the Si53350A, Si53354A, and Si53352A models, differing primarily in the number of outputs provided. All variants share the same automotive qualification and core electrical characteristics.

Clock Buffers, Drivers Replacement Considerations

Direct replacements include other members of the Si5335x family such as the Si53350A-D01AM (10 outputs), Si53354A-D01AM (4 outputs), and Si53352A-D01AM (2 outputs). Ensure the replacement matches the required output count and pin-out compatibility.
