PM4328 TECT3

HIGH DENSITY T1/E1 FRAMER

AND M13 MULTIPLEXER

Pin Name

Type Pin Function

No.

TMS

Input C2 Test Mode Select (TMS). This signal controls the test

operations that can be carried out using the IEEE

P1149.1 test access port. TMS is sampled on the

rising edge of TCK. TMS has an integral pull up

resistor.

TDI

Input C4 Test Data Input (TDI). This signal carries test data into

the TECT3 via the IEEE P1149.1 test access port. TDI

is sampled on the rising edge of TCK. TDI has an

integral pull up resistor.

TDO

Output B3

Test Data Output (TDO). This signal carries test data

out of the TECT3 via the IEEE P1149.1 test access

port. TDO is updated on the falling edge of TCK. TDO

is a tri-state output which is inactive except when

scanning of data is in progress.

TRSTB

Input B1 Active low Test Reset (TRSTB). This signal provides

an asynchronous TECT3 test access port reset via the

IEEE P1149.1 test access port. TRSTB is a Schmitt

triggered input with an integral pull up resistor. TRSTB

must be asserted during the power up sequence.

Note that if not used, TRSTB must be connected to the

RSTB input.

Miscellaneous Pins

NO CONNECT

A1 No Connect. These pins are not connected to any

B2 internal logic.
