Hello,
My customer will test 10Base-Te TP_Idle with Compliance Test Register(0x0027)
According to datasheet, Compliance Test Register(0x0027) is following.
Table 46. 0x0027 Compliance Test Register (COMPT)
Bit[4] in Register 0x0027 = 1, Enables 10Base-Te Test Patterns.
Bit[4] in Register 0x0428 = 1, Enables 100Base-TX Test Modes
Bits[3:0] select the 10Base-Te test pattern, as follows:
0000 = Single NLP
0001 = Single Pulse 1
0010 = Single Pulse 0
0011 = Repetitive 1
0100 = Repetitive 0
0101 = Preamble (repetitive ‘10’)
0110 = Single 1 followed by TP_IDLE
0111 = Single 0 followed by TP_IDLE
1000 = Repetitive ‘1001’ sequence
1001 = Random 10Base-Te data
1010 = TP_IDLE_00
1011 = TP_IDLE_01
1100 = TP_IDLE_10
1101 = TP_IDLE_11
(Question)
About TP_IDLE test pattern bits (Below)
0110 = Single 1 followed by TP_IDLE
0111 = Single 0 followed by TP_IDLE
1010 = TP_IDLE_00
1011 = TP_IDLE_01
1100 = TP_IDLE_10
1101 = TP_IDLE_11
(1) What is the difference between these bit (test pattern )settings?
(2) Which bit(test pattern ) should they use for TP_Idle test?
Regards,
