NJ88C33
Frequency Synthesiser (I2C BUS Programmable)
Advance Information
Fig.2 Simplified block diagram of NJ88C33
The NJ88C33 is a synthesiser circuit fabricated on Zarlink
Semiconductor's 1.4 micron CMOS process, assuring very
high performance. It is I2C compatible and can also be
programmed at up to 5MHz. It contains a 16-bit R counter, a
12-bit N counter and a 7-bit A counter.
A digital phase comparator gives improved loop stability
with current source outputs to reduce loop components. A
voltage doubler is provided for the loop driver to improve
control voltage range to the VCO when operating at low supply
voltages.
