SY75602BTWL-TR

Clock Buffers, Drivers Overview

The SY75602BTWL-TR is a two-output PCIe clock buffer from Microchip Technology, designed for PCIe Gen1 through Gen5 applications. It features ultra-low additive jitter of 10 fs RMS at PCIe Gen5 speeds and supports input frequencies up to 250 MHz. The device outputs Low Power HCSL signals with embedded 100Ω differential termination resistors. It operates on 1.8V, 2.5V, or 3.3V supplies (±10% tolerance) and includes an internal LDO for power noise rejection. Packaged in an 8-lead VDFN (1.4 mm x 1.6 mm), it functions within an extended temperature range of –40°C to +105°C.

Clock Buffers, Drivers Feature Summary

• Ultra-low additive jitter: 10 fs RMS (PCIe Gen5), 20 fs RMS (Gen3/Gen4), 52 fs (12 kHz–20 MHz band).
• Embedded 100Ω differential series termination resistors for LP-HCSL outputs.
• Supports 1.8V, 2.5V, and 3.3V power supplies with ±10% tolerance.
• Accepts DC-coupled HCSL inputs and AC-coupled PECL, LVDS, and CML inputs.

Clock Buffers, Drivers Applications

• PCIe Graphics Cards
• PCIe Based SSD drives
• Servers

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'W' corresponds to the specific tape-and-reel packaging configuration required for automated assembly. Confirm that the 'B' suffix indicates the 100Ω embedded termination variant suitable for your PCB trace impedance requirements. Ensure the component meets RoHS compliance standards as indicated by the manufacturer's documentation.

Clock Buffers, Drivers Selection Notes

Select the SY75602BTWL-TR when a compact 1.4 mm x 1.6 mm package is required for two-channel clock distribution. Choose this part over the 'A' suffix variant if the design utilizes 100Ω differential transmission lines rather than 85Ω. This device is appropriate for systems requiring glitch-free operation without individual output enable pins, which are available in the SY75603/604 families.

Clock Buffers, Drivers Part Context

This component belongs to the SY75602A/02B family of industry-leading PCIe clock buffers. It is distinguished by its small form factor and integrated termination, reducing external component count compared to traditional current-based HCSL buffers. It serves as a common clock and SRIS solution for high-speed serial interfaces.

Clock Buffers, Drivers Replacement Considerations

The SY75602ATWL-TR is a direct functional substitute but features 85Ω embedded termination resistors instead of 100Ω. Verify PCB impedance matching before swapping. Other family members like SY75603B or SY75604B offer additional outputs and per-output enable controls but require larger packages.
