Microchip Technology SY75602, SY75603, SY75604 PCIe Clock Buffers

Microchip Technology SY75602, SY75603, and SY75604 PCIe Clock Buffers are fanout buffers with an ultra-low additive jitter of 10fs for PCIe 5.0, 20fs for PCIe 3.0/4.0, and 52fs in the 12kHz to 20MHz band. The SY75602, SY75603, and SY75604 Clock Buffers can be used in all PCIe 1/2/3/4/5 common clock and SRIS applications. These devices have embedded low-dropout regulators (LDO) for superior power noise supply rejection. The SY75602, SY75603, and SY75604 Clock Buffers support 1.8V, 2.5V, and 3.3V supplies with a tolerance of ±10%, which exceeds ±9% required by PCIe Card Electro Mechanical Specification.

The two-output SY75602 PCIe Clock Buffers are offered in a miniature 1.4mm x 1.6mm VDFN package. The two-output SY75603 and four-output SY75604 are housed in a compact 3.0mm x 3.0mm VQFN package. The SY75603 and SY75604 also feature glitch-free per-output enable/disable control hardware pins.

The Microchip Technology SY7560x PCIe Clock Buffers have an extended -40°C to +105°C operating temperature range.
