General Description

The SY75608 and SY75612 are industry-leading PCIe

clock buffers with ultra-low additive jitter:

• 6 fs (PCIe 6.0)

• 10 fs (PCIe 5.0)

• 20 fs (PCIe 3.0/4.0)

• 52 fs in the 12 kHz to 20 MHz band

They can be used in all PCIe 1/2/3/4/5/6 common clock

and SRIS applications.

SY75608 and SY75612 are, respectively, eight and

twelve output PCIe clock buffers with glitch free

per-output enable/disable control hardware pins.

Devices are packaged in 6 mm x 6 mm VQFN

(SY75608) and 8 mm x 8 mm VQFN (SY75612).

The SY75608/612 each have an embedded

low-dropout regulator (LDO) for superior power noise

supply rejection. They support 1.8V, 2.5V, and 3.3V

supplies with a tolerance of ±10%, which exceeds the

±9% required by the PCIe Card Electro Mechanical

Specification.

Both parts are available in the extended temperature

range of –40°C to +105°C. Both parts are also available

with customized configurations to meet the customer’s

needs. Please visit the ClockWorks Configurator to
