The ICS87322BI is a low skew, ÷1/÷2 3.3V LVPECL/ECL
Clock Generator. Using multiplexed/redundant clock inputs
the ICS87322BI is designed to translate most differential
signal levels to LVPECL/ECL levels.
The CLK_SEL input selects between CLK0, nCLK0 and CLK1,
nCLK1 as the active input. The divide select inputs, DIV_SELA,
DIV_SELB, DIV_SELC, DIV_SELD, control the output frequency
of each bank. The outputs can be utilized in the ÷1, ÷2 or a
combination of ÷1 and ÷2 modes. The master reset input can
be used to reset the internal dividers and disable the clock
outputs. Disabled outputs QAx, QBx, QCx and QDx will be
forced low. Disabled outputs nQAx, nQBx, nQCx and nQDx
will be forced high.
The ICS87322BI is characterized across the industrial
temperature range and over the supply voltage range of 3V
to 3.8V for LVPECL and -3.8V to -3V for LVECL/ECL.
Guaranteed output and part to part skew characteristics
make the ICS87322BI an excellent choice for clock
generator and clock distribution applications demanding
well defined performance and repeatability.
