PI6C484321

260MHz Crystal-to-3.3V Differential

LVPECL Frequency Synthesizer

Product Features

Description

• Dual differential 3.3V LVPECL outputs

The PI6C484321 is a dual output, 3.3V LVPECLFrequency Syn-

thesizer using crystal as the input source. The input source is can

beselectedfromeither LVTTL/LVCMOSlevelinput(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.

• Selectable crystal oscillator interface or LVCMOS/LVTTL

TEST_CLK

• Output frequency range: 53.33MHz to 366.67MHz

• Crystal input frequency range: 14MHz to 40MHz

• TEST_CLK freqeuncy range: 10MHz to 50MHz

• VCO range: 320MHz to 1.1GHz

• Parallel or serial interface for programming counter and

output dividers

• RMS period jitter: 3ps (typical)

• 3.3V supply voltage

• 0°C to 70°C ambient operating temperature

• Packages (Pb-free & Green available):

- 32-pin LQFP (FB)
