Description

5.0 kHz output. When not used, connect to VSS.

4.4 kHz output (10.24 MHz ÷ 2304). When not used, connect to VSS.

Power supply.

Crystal resonator (10.24 MHz).

Channel select pin.

Base unit/remote unit select pin.

R/B = ‘‘0’’ (VSS) ...... Remote unit

R/B = ‘‘1’’ (VDD) ...... Base unit

Used to stop the TX PLL at the standby mode to minimize current dissipation.

SB = ‘‘0’’ (VSS) ...... Standby mode. Only the RX and PLL are operated. The charge pump enters a

high-impedance mode.

SB = ‘‘1’’ (VDD) ...... The TX, RX and PLL are operated.

TX programmable divider input pin.

RX programmable divider input pin.

TX charge pump output pin.

RX charge pump output pin.

LSI test input pin. Connected to VSS.

TX PLL unlock signal output pin.

When the phase difference becomes tD (= 6.25 µs.) or more, 5.6 ms. output pulse is delivered at the LDT pin.
