The NJ88C50 is a low power integrated circuit, designed
as the heart of a fast locking PLL subsystem in a mobile radio
application. It is manufactured on Mitel Semiconductor 1.4
micron double polysilicon CMOS process, which ensures that
low power and low noise performance is achieved. The device
contains two synthesisers, one for the generation of VHF
signals up to 125MHz and a second for UHF (when used with
a mulitmodulus prescaler such as the SP8713/14/15). The
main synthesiser has the capability of driving a dual speed
loop filter and also can perform Fractional-N interpolation.
Both synthesisers use current source outputs from their
phase detectors to minimise external components. Various
sections may be powered down for battery economy.
FEATURES
30MHz main synthesiser
125MHz auxiliary synthesiser
Programmable output current
from phase detector - up to 10mA
High input sensitivity
Fractional-N interpolator
Supports up to 4 modulus prescalers
