SY75608/612

8 or 12 Output Ultra-Low Additive Jitter

PCIe 1/2/3/4/5/6 Clock Buffer

Features

General Description

• Eight (SY75608) and Twelve (SY75612) PCIe 1.0,

2.0, 3.0, 4.0, 5.0, and 6.0 Compliant Outputs

The SY75608 and SY75612 are industry-leading PCIe

clock buffers with ultra-low additive jitter:

• Ultra-Low Additive Jitter: 10 fs (PCIe Gen5)

• Supports Frequencies of Up to 250 MHz

• Transparent for Spread Spectrum

• 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

• Supports 1.8V ±10%, 2.5V ±10%, and 3.3V ±10%

Power Supplies

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

and SRIS applications.

• Outputs Low Power HCSL with Embedded

Termination Resistors

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).

• Selectable Pin or I²C Bus Control

• Individual Glitch Free Output Enable (OExb)

Control Pins

• Accepts DC-Coupled HCSL Input Signal and

AC-Coupled PECL, LVDS, and CML Input Signals

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.

• Extended Temperature Range: –40°C to +105°C

• 6 mm x 6 mm VQFN (SY75608) and

8 mm x 8 mm VQFN (SY75612) package

Applications

• Cloud and High-Performance Computing

• PCIe-Based SSD Drives

• PCIe Switches

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

design your particular specifications.
