RTC clock synchronization buffer driver delay chip

The NB3N3020 is a high precision, low phase glitch selectable clock multiplier. The device operates from a 5.0-27 MHz fundamental mode parallel resonant crystal, or a 2.0-210 MHz LVCMOS single-ended clock source, to generate a differential LVPECL output and a single-ended LVCMOS/LVTTL output at a selectable clock output frequency that is 1/4 of the input clock frequency multiple. Three 3-level LVCMOS/LVTTL single-ended select pins set one of 26 possible clock multipliers. The LVCMOS/LVTTL output enable (OE) pin tri-states the clock output when low. The device is packaged in a 5.0 x 4.4 mm TSSOP-16 package.
