AMIS-52100
Low-Power Transceiver with Clock and Data Recovery
Data Sheet
8.3 LPFILT, Loop Filter
The LPFILT pin connects the AMIS-52100 internal phase lock loop (PLL) frequency synthesizer to an external loop filter. An external
loop filter allows the design engineer to optimize the operation of the AMIS-52100 to meet the requirements of their product application.
For more information see the AMIS application note: “Extending to Frequencies outside the 403MHz Target”.

8.4 RSSI/BG, Analog Output
The RSSI/BG pin is used to output the signal from the RSSI circuits, the output of the voltage from the bandgap voltage reference or a
bypass capacitor node. The RSSI output is a true analog representation of the received signal level. The pin can also be programmed
to output the voltage of the bandgap voltage reference. When using the AMIS-52100 in the clock and data recovery mode, a capacitor
needs to be connected from the RSSI/BG pin to ground. A typical value for this capacitor is 2.2nF. Additional information on the CDR
function can be found later in this document. Table 12 presents the registers that control the function of the RSSI/BG pin.

8.5 CREF, Current Reference Bias
A resistor must be connected to the AMIS-52100 CREF pin to provide a current bias to the internal bandgap voltage reference circuit. It
is critical that this resistor be a 33.2K
with one percent or better tolerance for proper operation of the bandgap voltage reference.
R(Bias) = 33.2K
