Description

The 9EX21801 provides 18 output clocks for PCIe Gen2

(100MHz) or QPI (133MHz) applications. The 9EX21801 has 4

selectable SMBus addresses, and dedicated CKPWRGD/PD#

and VDDA pins for easy board design. A differential CPU clock

from a CK410B+ main clock generator, such as the 932S421,

drives the 9EX21801. In fanout mode, the 9EX21801 provides

outputs up to 400MHz.

Features/Benefits

• Supports output clock frequencies up to 400 MHz

• 4 Selectable SMBus addresses

• SMBus address is independent of PLL operating mode

• Dedicated CKPWRGD/PD# and VDDA pins ease board

design

• Available in industrial temperature range (-40°C to +85°C)
