Pin Description
F1 : 5.0kHz output. When not used, connect to V
SS
.
F2 : 4.4kHz output (10.24MHz÷2304). When not used, connect to VSS.
VDD, VSS : Power supply.
XIN, XOUT : Crystal resonator (10.24MHz).
D1 to D4 : Channel select pin.
R/B : Base unit/remore unit select pin.
R/B= “0” (V
R/B= “1” (V
)............ Remote unit
SS
)........... Base unit
DD
SB : Used to stop the TX PLL at the standby mode to minimize current drain.
SB= “0” (VSS) ............. The charge pump enters a high-impedance mode.
Standby mode. Only the RX PLL is operated.
SB= “1” (V
) ............ The TX, RX PLL are operated.
DD
PIT : TX programmable divider input pin.
PIR : RX programmable divider input pin.
PDT : TX charge pump output pin.
PDR : RX charge pump output pin.
TEST : IC test input pin. Connected to V
SS
.
LDT : TX PLL unlock signal output pin.
