4.1 Types of I/O Interfaces
The TXN31015D2 Optical Transceiver has the following types of I/O interfaces.
- C M L i n t e r f a c e
- T T L i n t e r f a c e High-speed I/Os use the CML interface, while control signals use the TTL interface. Proper termination of I/Os is required for good signal integrity. If I/Os (particularly the CML I/Os) are not terminated properly, then jitter increases significantly due to reflection from impedance mismatches.
4.2 CML Termination
- Internal termination. For the TXN31015D2 Optical Transceiver receiver output, the SerDes interface provides an internal termination resistor.
- External termination. For the proper external termination of the SerDes interface, refer to the SerDes specification.

6.0 Digital Diagnostic Monitoring Interface

- Section 6.1, “Overview of Digital Diagnostic Monitoring Interface” on page 18
- Section 6.2, “General Memory Map Descriptions” on page 19
- Section 6.3, “Alarm and Warning Fields for 2-Wire Interface Address A2h” on page 20
- Section 6.4, “A/D Fields for 2-Wire Interface Address A2h” on page 22
6.1 Overview of Digital Diagnostic Monitoring Interface
The TXN31015D2 Optical Transceiver supports the 2-wire serial communication protocol. The TXN31015D2 Optical Transceiver has a digital diagnostic monitoring interface that is an extension of the serial ID interface defined in the Gigabit Interface Converter (GBIC) specification and the SFF Transceiver MultiSource Agreement (MSA) referenced in Section 1.0, “Introduction” on page 7.
- Standard SFF serial ID interface. The standard SFF serial ID interface (the memory map for which is in Table 12, “Memory Map – 2-Wire Address Range Descriptions” on page 19) provides access to identification information using the 8- bit address 1010000X (A0h). The serial identification information describes information such as the following for the TXN31015D2 Optical Transceiver: capabilities, standard interfaces, and manufacturer information.
- Digital diagnostic monitoring interface. The digital diagnostic monitor interface (the memory map for which is in Table 12, “Memory Map – 2-Wire Address Range Descriptions” on page 19) is an extension of the standard serial ID interface. This interface, which uses the 8-bit address 1010001X (A2h) reserved for optical transceivers, allows real-time access to device-operating parameters while leaving unchanged the original serial ID memory map A0h. The digital diagnostic monitoring interface is backward compatible with both the GBIC specification and the SFF MSA. Note: For details on the 2-wire addresses A0h and A2h, refer to the SFF-8472 document referenced in Section 1.0, “Introduction” on page 7.
6.2 General Memory Map Descriptions
Table 12 lists descriptions of address ranges for the serial ID memory map.
- The 2-wire address A0h contains serial ID information defined by the SFF MSA.
- The 2-wire address A2h contains data related to the digital diagnostics, defined by the SFF-8472 document referenced in Section 1.0, “Introduction” on page 7.

7.0 Grounding Scheme
There are two types of grounding on the TXN31015D2 Optical Transceiver.
- Chassis ground. The LC “nose” and the TXN31015D2 Optical Transceiver housing chassis comprise the chassis ground, which is used to connect to the system chassis ground.
- Signal ground. On the TXN31015D2 Optical Transceiver, there are two separate signal grounds. The Receiver Ground pin (pin 1) on the TXN31015D2 Optical Transceiver is connected to the internal TXN31015D2 Optical Transceiver RX signal ground. The Transmitter Ground pin (pin 7) on the TXN31015D2 Optical Transceiver is connected to the internal TXN31015D2 Optical Transceiver TX signal ground.

For good EMI and ESD performance, Intel recommends connecting these two signal grounds as follows:
- Connect Pin 1 to the RX signal ground on the host board adaptor (HBA) printed circuit board.
- Connect Pin 7 to the TX signal ground on the HBA printed circuit board. Figure 4 shows a grounding application diagram for the TXN31015D2 Optical Transceiver. Proper grounding is critical for good EMI and ESD performance.
