700MHz, Differential-to-3.3V LVPECL Frequency Synthesizer
8432I-101
Data Sheet
GENERAL DESCRIPTION
The 8432I-101 is a general purpose, dual outp u t D i f fe r e n t i a l - t o - 3 . 3 V LV P E C L h i g h f r e q u e n c y synthesizer and a member of the family of High Performance Clock Solutions from IDT. The 8432I-101 has a selectable TEST_CLK or CLK, nCLK inputs. The TEST_CLK input accepts LVCMOS or LVTTL input levels and translates them to 3.3V LVPECL levels. The CLK, nCLK pair can accept most standard differential input levels. The VCO operates at a frequency range of 250MHz to 700MHz. The VCO frequency is programmed in steps equal to the value of the input differential or single ended reference frequency.
