Ground.
Ground of logic section at PLL.
LBD
Low Battery Detecting output. ( Selectable 3.45V, 3.3V, 3.0V, 2.2V, 2.0V ).
During the normal operation, output level is low, but it is high at low battery
detection. As this pin is an open collector type, it requires a pull - up resister.
These pins are serial interface terminals for programming reference counter,
auxiliary reference counter, TX channel counter, RX channel counter and control
block that controls internal each block with test mode and power saving mode.

This pin bypasses AC elements at the feedback loop which come from the SUM
amp block of COMPRESSOR. A capacitor should be connected between this ter-
minal and GND. ( C = 2.2 uF )

AGIC
Input terminal of Splatter filter amp.
SFI
SFO
Output terminal of Splatter filter amp.
LDT : Output terminal of transmitter lock detector in PLL block. Output is low
if PLL is in lock state and is high if PLL is in unlock state.
CDO : As an output terminal of the carrier detector buffer, connected to (RSSI )
terminal of MICOM. This pin outputs the contents of Meter Driver buffer
which is turned on / off, according to the signal level detected by Meter
Driver.
