PI6CV304 / PI6CV2304

Description

Pericom’sPI6CV304andPI6CV2304arelow-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.

Features

• 140MHz operation (PI6CV2304)

• 160 MHz operation (PI6CV304)

• 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 (–40°C to 85°C)

• 3.3V power supply

• Packaging (Pb-free & Green available)

– 8-pin TSSOP (L)

– 8-pin SOIC (W)
