PI6C484321
260MHz Crystal-to-3.3V Differential
LVPECL Frequency Synthesizer
Description
The PI6C484321 is a dual output, 3.3V LVPECL Frequency Syn-
thesizer using crystal as the input source. The input source is can
be selected from either LVTTL/LVCMOS level input (TEST_CLK
pin) or crystal inputs. The VCO operates at a frequency range of
320MHz to 1.1GHz. The VCO frequency is programmed in steps
equal to the value of the input reference or crystal frequency. The
VCO and output frequency can be programmed through a simple
2-wire serial interface or through 11-bit parallel interface. The low
phase noise characteristics of the PI6C484321 make it an ideal
clock source for Fibre Channel 1 (FC1), Fibre Channel 2 (FC2), 10
Gigabit Fibre Channel (10GFC), Gigabit Ethernet and 10 Gigabit
Ethernet (10GbE) applications.
