10  
F0/CLD Frame Pulse/C-Channel Load (Digital). In DN mode a 244 ns wide negative pulse input  
for the MASTER indicating the start of the active channel times of the device. Output for  
the SLAVE indicating the start of the active channel times of the device. Output in MOD  
mode providing a pulse indicating the start of the C-channel.

DSTi/Di Data ST-BUS In/Data In (Digital). A 2.048 Mbit/s serial PCM/data input in DN mode. In  
MOD mode this is a continuous bit stream at the bit rate selected.  
F0o/RCK Frame Pulse Out/Receive Bit Rate Clock output (Digital). In DN mode a 244 ns wide  
negative pulse indicating the end of the active channel times of the device to allow daisy  
chaining. In MOD mode provides the receive bit rate clock to the system.

21  
C4/TCK Data Clock/Transmit Baud Rate Clock (Digital). A 4.096 MHz TTL compatible clock  
input for the MASTER and output for the SLAVE in DN mode. For MOD mode this pin  
provides the transmit bit rate clock to the system.  
OSC2  
Oscillator Output. CMOS Output.
