Notes
1. Source impedance = 50
2. Virtual earth input amplifier, therfore low impedance for small signals. Impedance is high once signal amplitude exceeds
typically ±0.125V.
3. Input amplifier may become unstable for higher values of Z

Notes
1. The current set on pin RSA will be scaled up on chip by a factor of 3 to give the value of the auxiliary phase detector
output.
2. The current set on pin RSM will be scaled down on chip by a factor of 32 to provide the current
Ibo
to the main phase
detector which gives the outputs
Iprop
and
Iint
.
3. The current set on pin RSC will be scaled down on chip by a factor of 128 to provide the current
Ico
to the main phase
detector which gives the outputs
Icomp
and
Icomp 2
.
4. The voltage on each of the three current setting pins (RSA, RSM, RSC) is approximately 4V.
Therefore to give a typical current of 32μA on RSM for example, a 125k
resistor connected between the pin and GND
would be required.
