Ⅳ . Pin Descriptions

Notes:

1. Circuit ground is internally isolated from chassis ground.

2. TFAULT is an open collector/drain output, which should be pulled up with a 4.7k – 10k Ohms resistor on the

host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high output indicates a

transmitter fault caused by either the TX bias current or the TX output power exceeding the preset alarm

thresholds. A low output indicates normal operation. In the low state, the output is pulled to <0.8V.

3. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.

4. Should be pulled up with 4.7k - 10 kohms on host board to a voltage between 2.0V and 3.6V. MOD_ABS pulls

line low to indicate module is plugged in.

5. Transceiver data rate selected through the 2-wire bus in accordance with SFF-8472 Rev. 10.5. Soft RS0 is set at

Bit3, Byte 110, Address A2h. Soft RS0 default state on power up is ‘0’ LOW, and the state is reset following a

power cycle. Writing ‘1’ HIGH selects max. data rate operation. Transceiver data rate is the logic OR of the

input state of the RS0 pin and soft RS0 bit. Thus, if either the RS0 pin OR the soft RS0 bit is HIGH then the

selected data rate will be 5 Gb/s.

6. Loss Of Signal is LVTTL. Should be pulled up with 4.7kΩ – 10kΩ on host board to a voltage between 2.0V and

3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.

Ⅴ . Digital Diagnostic Functions

SINOVO SOSP-3150-02 transceivers support the 2-wire serial communication protocol as defined in the SFP+ MSA.

The standard SFP+ serial ID provides access to identification information that describes the transceiver’s capabilities,

standard interfaces, manufacturer, and other information.

Additionally, SINOVO SFP+ transceivers provide a unique enhanced digital diagnostic monitoring interface, which

allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted

optical power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm

and warning flags, which alerts end-users when particular operating parameters are outside of a factory set normal range.

The SFP+ MSA defines a 256-byte memory map in EEPROM that is accessible over a 2-wire serial interface at the 8

bit address 1010000X (A0h). The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h),

so the originally defined serial ID memory map remains unchanged.

The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller

(DDTC) inside the transceiver, which is accessed through a 2-wire serial interface. When the serial protocol is activated,

the serial clock signal (SCL, Mod Def 1) is generated by the host. The positive edge clocks data into the SFP+

transceiver into those segments of the E2PROM that are not write-protected. The negative edge clocks data from the

SFP+ transceiver. The serial data signal (SDA, Mod Def 2) is bi-directional for serial data transfer. The host uses SDA

in conjunction with SCL to mark the start and end of serial protocol activation. The memories are organized as a series

of 8-bit data words that can be addressed individually or sequentially.
