Signal Name:
T3E3MS
Signal Description:
T3/E3 Mode Select Input
Signal Type:
Input
This signal determines whether the DS3112 will operate in either the T3 mode or the E3 mode. It acts as a
global control bit for the entire DS3112. This signal should be set into the proper state before a hardware
reset is issued via the
RST signal. This input is coupled with the G.747E input to create a special test
mode whereby all the outputs are tri-stated (Table 2-3).
0 = T3 Mode
1 = E3 Mode
Signal Name:
G.747E
Signal Description:
G.747 Mode Enable Input
Signal Type:
Input

RST signal. This input is coupled with the T3E3MS input to create a
special test mode whereby all the outputs are tri-stated (Table 2-3).

Special Test Mode that tri-states all outputs.
JTRST must be driven
low for tri-state operation without power-up. Refer to note for
JTRST signal.

VDD
Signal Description:
Digital Positive Supply
Signal Type:
