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
