TSP-10G3A1EER

2.Shall be pulled up with 4.7K-10Kohms to a voltage between 3.15V and 3.45V on the host board.

7.Low Speed Electrical Hardware Pins

In addition to the 2-wire serial interface the XFP module has the following low speed pins for control and status:

•Mod_NR

•Mod_DeSel

•Interrupt

•TX_DIS

•Mod_ABS

•RX_Los

•P_Down/RST.

1 MOD_NR

The Mod_NR is an output pin that when High, indicates that the module has detected a condition that renders transmitter and or receiver data invalid, shall consist of logical OR of the following signals:

•Transmit Signal Conditioner Loss of Lock

•Transmitter Laser Fault

•Receiver Signal Conditioner Loss of Lock

Other conditions deemed valuable to the detection of fault may be added to the Mod_NR.

The Mod_NR output pin is an open collector and must be pulled to Host_Vcc on the host board.

2 MOD_DESEL

The Mod_DeSel is an input pin. When held Low by the host, the module responds to 2-wire serial communication commands. The Mod_DeSel allows the use of multiple XFP modules on a single 2-wire interface bus.

When the Mod_DeSel pin is “High”, the module shall not respond to or acknowledge any 2-wire interface communication from the host. Mod_DeSel pin must be pulled to VCC3 in the module.

In order to avoid con.icts, the host system shall not attempt 2-wire interface communications within the Mod_DeSel assert time after any XFP modules are deselected. Similarly, the host must wait at least for the period of the Mod_DeSel deassert time before communicating with the newly selected module. The assertion and de-assertion periods of different modules may overlap as long as the above timing requirements are met.

3 INTERRUPT

Interrupt is an output pin. When “Low”, indicates possible module operational fault or a status critical to the host system. The Interrupt pin is an open collector output and must be pulled up to Host_Vcc the host board.

4 TX_DIS

TX_DIS is an input pin. When TX_DIS is asserted High, the XFP module transmitter output must be turned off. The TX_DIS pin must be pulled up to VCC3 in the XFP module.
