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. 160 MHz operation Low noise, low skew: 150ps max Fast rise/fall time: 1.0ns typ. Fast propagation delay: 2.0ns typ. 5V I/O tolerant input Industrial temperature (-40C to 85C) 3.3V power supply Packaging: - 8-pin TSSOP (L) - 8-pin SOIC (W) 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 impedance is 20-Ohms.
