SY75608集成电路（IC）的时钟缓冲器驱动器规格书PDF中文资料

SY75608属于集成电路（IC）的时钟缓冲器驱动器。由美国微芯科技公司制造生产的SY75608时钟缓冲器，驱动器时钟缓冲器和驱动器集成电路产品族中的产品用于帮助信号在系统中传输，常用作频率/时间参考信号，以同步系统内的活动。尽管这些器件最常用到的功能就是缓冲（即，为使信号不受驱动负载的影响而从某个信号源复制信号），但是该产品族中的某些器件还能执行其他功能，例如选择性改变缓冲信号路径、按某个整数值分割信号频率，或进行所用电信号格式转换。

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
