Description
1
2
GND
Ground for the IF PLL analog and digital circuits, MICROWIRE
TM, Ftest/LD and
oscillator circuits.
2
3
FinIF
I
IF PLL prescaler input. Small signal input from the VCO.
3
4
EN
I
Chip Enable input. High Impedance CMOS input. When this pin is set HIGH,
the RF and IF PLLs are powered up. Powerdown is then controlled through the
MICROWIRE. When this pin is set LOW, the device is asynchronously powered
down and the charge pump output is forced to a high impedance state
(TRI-STATE).
4
5
CPoutIF
O
IF PLL charge pump output. The output is connected to the external loop filter,
which drives the input of the IF VCO.
5
6
ENosc
I
Oscillator Enable input. High impedance CMOS input. When this pin is set
HIGH, the oscillator buffer is always powered up, independent of the state of
the EN pin. When this pin is set LOW, the OSCout/ FLoutIF pin functions as an
IF Fastlock output, which connects a resistor in parallel to R2 of the external
loop filter.
6
7
OSCout/
FLoutIF
O
Oscillator output/ IF PLL Fastlock output. The output configuration is dependent
on the state of the ENosc pin. When ENosc is set LOW, the pin functions as an
IF Fastlock output, which connects a resistor in parallel to R2 of the external
loop filter. This configuration also functions as a general purpose CMOS
TRI-STATE output. When ENosc is set HIGH, the pin functions as an oscillator
output so that an external crystal can be used.
7
8
OSCin
I
Reference oscillator input. The input has an approximate Vcc/2 threshold and is
driven by an external AC coupled source.
8
9
Vcc
Power supply bias for the RF PLL digital circuits and oscillator circuits. Vcc may
range from 2.25V to 2.75V. Bypass capacitors should be placed as close as
possible to this pin and be connected directly to the ground plane.
9
10
Ftest/LD
O
Programmable multiplexed output. Functions as a general purpose CMOS
TRI-STATE output, N and R divider output, RF/ IF PLL push-pull analog lock
detect output, RF/ IF PLL open-drain analog lock detect output, or RF/ IF PLL
digital filtered lock detect output.
