NB3N3020
3.3 V, LVPECL/LVCMOS
Clock Multiplier
Description
The NB3N3020 is a high precision, low phase noise selectable clock
multiplier. The device takes a 5 – 27 MHz fundamental mode parallel
resonant crystal or a 2 210 MHz LVCMOS single ended clock source
and generates a differential LVPECL output and a single ended
LVCMOS/LVTTL output at a selectable clock output frequency which
is a multiple of the input clock frequency. Three trilevel (Low, Mid,
High) LVCMOS/LVTTL single ended select pins set one of 26
possible clock multipliers. The LVCMOS/LVTTL output enable
(OE1) tristates the LVCMOS/LVTTL clock output (CLK1) when
low. When the LVTTL/LVCMOS output enable (OE2) is LOW,
LVPECL CLK2 is forced LOW and LVPECL CLK2 is forced HIGH.
This device is housed in 5 mm x 4.4 mm narrow body TSSOP 16 pin
package.

Description
Frequency select input 0. When left open, defaults to VDD/ 2. See output select Table 2
for details.
Frequency select input 1. When left open, defaults to VDD/ 2. See output select Table 2
for details.
Frequency select input 2. When left open, defaults to VDD/ 2. See output select Table 2
for details.
Positive supply voltage pins are connected to +3.3 V supply voltage.
Crystal or Clock input. Connect to 5 27 MHz crystal source or 2 – 210 MHz single
ended clock. See Table 2.
Crystal input. Connect to a 5 – 27 MHz crystal or leave unconnected for clock input. See
Table 2.
Output enable input that synchronously tristates CLK1 output when low. Internal pullup
resistor to VDD.
Output enable input that when LOW synchronously controls LVPECL outputs by forcing
CLK2 LOW and CLK2 HIGH. Internal pullup resistor to VDD.
Ground 0 V. These pins provide GND return path for the devices.
Inverted clock output. Clock frequency equals input frequency times multiplier.
Noninverted clock output. Clock frequency equals input frequency times multiplier.
Clock Output. Clock frequency equals input frequency times multiplier.
