Preliminary specication
ATSC 8-VSB demodulator and decoder
TDA8960
Boundary scan interface
The TDA8960 Test Access Port (TAP) conforms to
the
“IEEE 1149.1 Joint Test Action Group (JTAG)” standard.
It is used for board level testing of integrated circuits and
for testing the internals of an integrated circuit. The JTAG
standard defines on-chip test logic, which consists of an
instruction register, a group of test data registers including
a bypass register and a boundary scan register, four
dedicated pins collectively called the Test Access Port
(TAP) and a TAP controller.
INSTRUCTION REGISTER
The instruction register consists of four bits without parity.
There are five defined public instructions; see Table 5.
Table 5
Public instruction codes
Notes
1. The bypass instruction provides a minimum length (1-bit) serial path between the TDI and TDO pins when no test
operation is required.
2. This instruction can be used to take a sample of the inputs and outputs during normal operation of the component.
It can also be used to preload data values into the latched outputs of the boundary scan register.
3. This instructions allows testing off-chip circuitry and board level interconnections.
4. This instruction allows low speed, static testing of the on-chip logic. It can also be used after the chip is mounted on
a printed circuit board.
5. This instruction will return the manufacturer ID, part number code and version code. For the TDA8960 the
manufacturer ID is ‘B00000010101’, the part number code is ‘SVSB’ and the version code is ‘D1’.
In addition three private instructions are implemented to control different test modes; see Table 6.

characterization mode
In the characterization mode the IC is scan-testable in the
same way as in the scan test mode. However the outputs
are not switched to the scan chain outputs. The outputs
retain their functionality. It is now possible to scan test
pattern through the logic and to verify if the timing
constrains at the outputs are met.
EXTERNAL INTERFACE
The TAP consists of five pins as shown in Table 7.
