ICS8402I

350MHZ, CRYSTAL-TO-LVCMOS/LVTTL FREQUENCY SYNTHESIZER

IDT™ / ICS™ LVCMOS/LVTTL FREQUENCY SYNTHESIZER

7

ICS8402AYI REV. A OCTOBER 16, 2007

NOTE 1: Outputs terminated with 50

NOTE 1: For the input crystal and TEST_CLK frequency range, the M value must be set for the VCO to operate within the 250MHz to

700MHz range. Using the minimum input frequency of 12MHz, valid values of M are 21

≤ M ≤ 58. Using the maximum input frequency of

40MHz, valid values of M are 7

≤ M ≤ 17.
