FIGURE 2-7: CRYSTAL CLOCKING OPTION
2.6 LINE INTERFACE CONNECTOR OPTIONS
The KSZ8081 has a conventional RJ-45 UTP Ethernet connector, but there are three
connector options for the KSZ8061:
1. J1: Ethernet RJ-45
2. J2: TE MQS-4, part number 1379165-1 (Mating receptacle is 1379029-1)
3. J3: Sumitomo TS series 16-pin, part number 6098-6793 (Mating receptacle is
6098-4008)
Table 2- 1 lists the signal connections for each connector. Also refer to the schematic or
PCB layout file since connector pin numbering may not be standardized.
CAUTION
The silkscreen labels on the bottom of the board for R62, R91 and R92 are incorrect.
The middle resistor is R62. R91 is closer to C9, and R92 is closer to C10. The image
below shows the correct locations of R62, R91, and R92.
