SYA75604ATWLVAO

Overview

The SYA75604ATWLVAO is an automotive-grade, four-output PCIe clock buffer designed for ultra-low additive jitter applications. It supports frequencies up to 250 MHz and complies with PCIe Gen 1 through Gen 5 standards. The device features Low Power HCSL (LP-HCSL) outputs with embedded 85Ω differential termination resistors. It accepts DC-coupled HCSL inputs as well as AC-coupled PECL, LVDS, and CML signals. Operating voltage ranges from 1.62 V to 3.63 V, supporting 1.8V, 2.5V, and 3.3V supplies with ±10% tolerance. The component includes individual glitch-free output enable pins and operates within a temperature range of –40°C to +105°C.

Feature Summary

• Ultra-low additive jitter: 10 fs RMS for PCIe Gen 5, 20 fs for Gen 3/4, and 52 fs in the 12 kHz to 20 MHz band.
• Four LP-HCSL outputs with integrated 85Ω differential termination resistors.
• Glitch-free per-output enable/disable control via active-low OExb pins synchronous with the input clock.
• Embedded low-dropout regulators (LDO) provide superior power supply noise rejection.

Applications

• Advanced Driver Assistance Systems (ADAS)
• PCIe-based Solid State Drives (SSD)
• Automotive Infotainment Systems

Procurement Notes

Verify that the specific ordering suffix matches the required package media type. The 'TWL' suffix indicates a 16-lead 3 mm x 3 mm VQFN package with wettable flanks. The '-VAO' suffix denotes standard automotive grade compliance. Confirm whether the tube or reel configuration is required for the manufacturing process, as these are distinct part variants within the same family.

Selection Notes

Select the SYA75604A variant specifically when 85Ω embedded termination is required; the SYA75604B variant provides 100Ω termination. Ensure the design utilizes the 3 mm x 3 mm VQFN footprint compatible with the 16-lead package outline. Verify that the input signal source supports the specified voltage levels and coupling methods, as the device accepts both single-ended and differential inputs.

Part Context

This component belongs to the SYA75603A/B and SYA75604A/B family of automotive PCIe clock buffers. It shares core electrical characteristics with the two-output SYA75603A/B but provides four independent outputs. All parts in this series are designed to meet automotive reliability standards and support the full spectrum of PCIe generations from 1.0 to 5.0.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip technical support for cross-reference information regarding alternative timing solutions.
