9EX21501A集成电路（IC）的应用特定时钟/定时规格书PDF中文资料

描述 Description

The ICS9EX21501 provides 15 output clocks for PCIe Gen2

(100MHz) or QPI (133MHz) applications. A differential CPU clock

from a CK410B+ main clock generator, such as the ICS932S421,

drives the ICS9EX21501. In fanout mode, the ICS9EX21501

provides outputs up to 400MHz. A 2:1 input mux allows selection

between local and remote clock sources.

Features/Benefits:

• Output clock frequencies up to 400 MHz/supports wide

range of applications

• 4 Selectable SMBus addresses/multiple devices can share

SMBus segment

• SMBus address independent of PLL operating mode/

maximum flexibility

• Dedicated CKPWRGD/PD# and VDDA pins/Easy board

design

• 8 Dedicated OE# and 2 Group OE# pins/Support for

hardware clock management
