Description
The PI6C49015 is a high performance networking clock
generator which generates PCIe 2.0 Compliant 100MHz HCSL
clock signals along with two LVCMOS 25MHz clock from either
25MHz crystal or reference input. This integrated solution is
ideal for Networking, Embedded systems and other systems that
require PCIe 1.0 and 2.0 HCSL signals and 25MHz clocks yet
small foot print.
Applications
ÎÎNetworking systems
ÎÎEmbedded systems
ÎÎOther systems
