9.2 PIN ASSIGNMENT
The “type” field gives the type of buffer used in the PTD:
CMOS
TTL
3STA
TTL/CMOS
TTL + 3STA
for CMOS input
for TTL input
for tri-state output
for TTL/CMOS output
for a bidirectional TTL input associated with a tri-state output
The “buffer” field gives the name of the GPS MA9000a buffer used in the PTD:
CMOSIP
TTLIP
BOP
TRIOUT
CSCHMITT
for input CMOS buffer
for input TTL buffer
for TTL/CMOS output buffer
for output tristate buffer
for input CMOS buffer with Schmitt trigger
The “pu/pd” field indicates if an internal pull up or pull down is present in the buffer.
Note: Internal pull-up or pull-down resistors should not be relied upon for proper operation and/or termination of
input levels under all operating conditions without prior consultation with GPS.
