SYA75603BTWLVAO

Overview

The SYA75603BTWLVAO is an automotive-grade PCIe clock buffer featuring two ultra-low additive jitter outputs. It supports PCIe Gen 1 through 5 with frequencies up to 250 MHz and delivers 10 fs peak-to-peak additive jitter for Gen 5 applications. The device incorporates embedded 100Ω differential termination resistors at the LP-HCSL outputs, eliminating external components. It accepts DC-coupled HCSL or AC-coupled PECL/LVDS/CML inputs and provides individual glitch-free output enable control via active-low pins. Powered by a single supply of 1.8V, 2.5V, or 3.3V (±10%), it includes internal LDOs for superior power noise rejection.

Feature Summary

• Ultra-low additive jitter: 10 fs (PCIe Gen 5), 20 fs (Gen 3/4), and 52 fs (12 kHz–20 MHz band).
• Two differential LP-HCSL outputs with integrated 100Ω termination resistors.
• Glitch-free per-output enable/disable control using active-low OExb pins.
• Automotive Grade 2 compliance with extended temperature range (-40°C to +105°C).

Applications

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

Procurement Notes

Verify that the 'B' suffix indicates the specific variant with 100Ω embedded output termination resistors. Confirm the 'TWL' package designation corresponds to the 16-lead 3 mm x 3 mm VQFN form factor. Ensure the 'VAO' suffix aligns with the required automotive qualification standards for the target application environment.

Selection Notes

Select this component when a two-channel fanout buffer is required for high-speed PCIe interfaces in automotive environments. The choice between the 'A' and 'B' variants depends on whether the design requires 85Ω or 100Ω embedded termination. This part is suitable for designs needing independent output gating without introducing glitches during state transitions.

Part Context

This device belongs to the SYA75603A/B family of PCIe clock buffers designed for automotive reliability. It shares the same core architecture and packaging as the SYA75603A but differs in its output impedance characteristics. The model is specifically engineered to meet the stringent jitter and power supply noise requirements defined by the PCIe Card Electro Mechanical Specification.
