NOTE:
Permanent device damage may occur if the above
Absolute Maximum Ratings
are exceeded. Functional operation should be restricted to the conditions as
detailed in the operational sections of this data sheet. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
PIN ASSIGNMENT
This device contains circuitry to protect the inputs against
damage due to high static voltages or electric fields. However,
it is advised that normal precautions be taken to avoid
application of any voltage higher than maximum rated voltages
to this high impedance circuit.

DUAL SERIAL INPUT PLL FREQUENCY SYNTHESIZER
WITH 600MHz PRESCALER
The Fujitsu MB1519 is a 600MHz dual serial input PLL (Phase Locked) frequency synthesizer
designed for cellular telephone and cordless telephone applications.
The MB1519 has two PLL circuits on a single chip: one for transmit and the other for reception.
Separate power supply pins are provided for the transmit and reception PLL circuits. Transmit
PLL contains a low sensitivity charge pump for ease of modulation and reception PLL contains a
high sensitivity charge pump for faster lock up time.
600 MHz dual modulus prescalers are on chip and enables a pulse swallow function.
It operates supply voltage of 3.0V typ. and dissipates 11mA typ. of current realized through the
use of Fujitsu’s unique U-ESBIC Bi-CMOS technology.
High operating frequency: fin = 600MHz
Low power supply voltage: V
CC
= 2.7 to 5.5V
Low power supply current: I
