Data slice reference level
The DSN pin is defined internally by the Slice volt-
age V
REF
. The DSN slice voltage can be offset from
the internal reference V
REF
by connecting a resistor
from the DSN pin to V
EE
and/or the peak detector
output.
For further information please refer to the Baseband
section of the Functional Description.
PLL loop filter connection
The phase detector output current is derived by two
internal current sources. The nominal linear average
output current is
1

μ
A (5
μ
A/radian).
For further information please refer to the Phase Lock
Loop VCO section of the Functional Description
Negative supply
Voltage controlled oscillator
The voltage controlled oscillator circuit is designed
from two cross coupled transistors. The centre fre-
quency of the VCO is set by the external tank circuit.
For further information please refer to the Voltage
Controlled Oscillator (VCO) Circuit Design / Layout
section of the Functional Description
Voltage controlled oscillator
Data Filter Output
The data filter is configured as a unity gain amplifier
with a low impedance output. Tracking of the received
baseband signal is achieved by an internal current
source.
For further information please refer to the Baseband
section of the Functional description.
