NB3N502
14 MHz to 190 MHz PLL
Clock Multiplier
Description
The NB3N502 is a clock multiplier device that generates a low jitter,
TTL/CMOS level output clock which is a precise multiple of the
external input reference clock signal source. The device is a cost
efficient replacement for the crystal oscillators commonly used in
electronic systems. It accepts a standard fundamental mode crystal or
an external reference clock signal. Phase−Locked−Loop (PLL) design
techniques are used to produce an output clock up to 190 MHz with a
50% duty cycle. The NB3N502 can be programmed via two select
inputs (S0, S1) to provide an output clock (CLKOUT) at one of six
different multiples of the input frequency source, and at the same time
output the input aligned reference clock signal (REF).
Features
• Clock Output Frequency up to 190 MHz
• Operating Range: VDD = 3 V to 5.5 V
• Low Jitter Output of 15 ps One Sigma (rms)
• Zero ppm Clock Multiplication Error
• 45% − 55% Duty Cycle
• 25 mA TTL−level Drive Outputs
• Crystal Reference Input Range of 5 − 27 MHz
• Input Clock Frequency Range of 2 − 50 MHz
• Available in 8−pin SOIC Package or in Die Form
• Full Industrial Temperature Range −40°C to 85°C
• These are Pb−Free Devices
