SYA75604BTWLVAO

Overview

The SYA75604BTWLVAO is a four-output PCIe clock buffer designed for automotive applications, compliant with PCIe Gen 1 through 5 standards. It features ultra-low additive jitter of 10 fs RMS at PCIe Gen 5 speeds and supports input frequencies up to 250 MHz. The device provides Low Power HCSL (LP-HCSL) outputs with embedded 100 Ohm differential termination resistors. It accepts DC-coupled HCSL inputs as well as AC-coupled PECL, LVDS, and CML signals. Powered by 1.8V, 2.5V, or 3.3V supplies, it includes individual glitch-free output enable controls and operates within an extended temperature range of -40°C to +105°C in a 16-lead VQFN package.

Feature Summary

• Four LP-HCSL outputs with embedded 100 Ohm differential termination resistors
• Ultra-low additive jitter: 10 fs RMS (PCIe Gen 5), 20 fs RMS (Gen 3/4)
• Supports PCIe Gen 1, 2, 3, 4, and 5 common clock and SRIS applications
• Glitch-free per-output enable/disable control via active-low OExb pins

Applications

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

Procurement Notes

Verify the specific ordering suffix against the datasheet product identification system. The 'TWL' suffix indicates a 16-lead 3 mm x 3 mm VQFN package with wettable flanks. The '-VAO' suffix denotes standard automotive qualification. Confirm whether the required quantity necessitates tube packaging (120 units) or tape and reel options, as availability may vary by media type.

Selection Notes

Select the SYA75604B variant specifically for designs requiring 100 Ohm embedded output termination; the SYA75604A variant provides 85 Ohm termination. Ensure the power supply voltage matches one of the supported levels (1.8V, 2.5V, or 3.3V) with ±10% tolerance. Verify that the input signal format (HCSL, PECL, LVDS, or CML) aligns with the device's input buffering capabilities and that the application requires four distinct clock outputs.

Part Context

This component belongs to the SYA75603A/B and SYA75604A/B family of ultra-low additive jitter PCIe clock buffers. While the SYA75603 variants provide two outputs, the SYA75604 series offers four outputs. All members share the same 3 mm x 3 mm VQFN footprint and core electrical characteristics, differing primarily in output count and embedded termination resistance values.

Replacement Considerations
