SI53354A-D01AM

Clock Buffers, Drivers Overview

The SI53354A-D01AM is a pin-selectable, automotive-grade clock buffer from Skyworks Solutions. It provides four outputs with selectable formats including LVCMOS, LVDS, LVPECL, and HCSL. The device operates within a frequency range of 10 to 250 MHz and supports dual inputs via an integrated 2:1 multiplexer. Built-in low-dropout regulators (LDOs) enhance power supply noise rejection. It features loss-of-signal monitoring and hardware output enable pins. Qualified under AEC-Q100 standards, it functions reliably across temperatures from -40°C to +105°C.

Clock Buffers, Drivers Feature Summary

• Four outputs with pin-selectable signal formats (LVCMOS, LVDS, LVPECL, HCSL)
• Integrated 2:1 input multiplexer for dual input capability
• Loss of signal (LOS) monitors for input clock verification
• Built-in LDOs for high PSNR and simplified design
• Hardware control pins for individual output enable/disable

Clock Buffers, Drivers Applications

• Infotainment systems
• Advanced Driver Assistance Systems (ADAS)
• Radar sensors
• Automated driving processing units
• Networking gateways

Clock Buffers, Drivers Procurement Notes

Verify the specific package type and temperature grade during procurement. Confirm that the pin-selectable configuration matches the required output format settings using the Format_SEL pins. Ensure compatibility with the target system's voltage levels for both core and output supplies before ordering.

Clock Buffers, Drivers Selection Notes

Select this part when a fixed-function, automotive-qualified buffer with multiple output format options is needed without custom programming. Compare against user-defined variants if specific voltage translation or unique pin assignments are required. Verify that the 10-250 MHz operating range meets the system clock requirements.

Clock Buffers, Drivers Part Context

This component belongs to the Si5335x family of universal clock buffers. It is one of several output configurations available in the series, which includes 2, 8, and 10-output versions. All members share similar automotive qualifications and internal LDO features but differ in pin count and output capacity.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family include SI53352A-D01AM (2 outputs), SI53358A-D01AM (8 outputs), and SI53350A-D01AM (10 outputs). For customized configurations, consider the Si53354BDxxxxx-AM series.
