Description
Pericom’s PI6CV304 and PI6CV2304 are low-skew, low- noise, high-
speed clock buffers and are ideal for computing, networking, and
communication applications. Application examples include PCI(X)
clock buffers in servers and workstations, PCI(X) Storage Area
Network (SAN), and RAID controllers. They are used for networking
and communications applications requiring 80 MHz for 10/100 Mbps
Ethernet and 125 MHz for Gigabit networking clocks.
To reduce EMI emission and power consumption, all outputs can be
disabled to 3-state by asserting a low signal to the OE (Output
Enable) pin.
PI6CV2304 output impedance is 30-ohms. PI6CV304 output imped-
ance is 20-ohms.
Applications
• 33 MHz PCI-to-133 MHz PCIX controllers
• 80 MHz for 10/100 Mbps Ethernet
• 125 MHz for Gigabit networking
• 155 MHz for Optical OC3/SDH/SONET
