General Description

The SY75602A/02B/03A/03B/04A/04B are industry

leading PCIe clock buffers with ultra-low additive jitter:

- 10 fs (PCIe 5.0)

- 20 fs (PCIe 3.0/4.0)

- 52 fs in 12 kHz to 20 MHz band

They can be used in all PCIe 1/2/3/4/5 common clock

and SRIS applications.

SY75602A/02B are the industry’s smallest

(1.4 mm x 1.6 mm VDFN) two output PCIe clock

buffers.

SY75603A/03B and SY75604A/04B are two and four

output PCIe clock buffers with glitch free per-output

enable/disable control hardware pins. Both devices are

packaged in 3 mm x 3 mm VQFN.

The devices have embedded low-dropout regulators

(LDO) for superior power noise supply rejection. They

support 1.8V, 2.5V, and 3.3V supplies with tolerance of

±10% which exceeds ±9% required by PCIe Card

Electro Mechanical Specification.

All six parts have extended temperature range:

–40°C to +105°C.
