2.5Gps SFP TRANSCEIVER MODULE

2.5Gbps S-16.1 / IR-1 SFP Transceiver with Digital Diagnostic

Monitoring Interface MF-2500FXD Series

1. Description

This transceiver is compliant with Small

Form-factor Pluggable (SFP) MSA, and

optimized for SDH S-16.1, / SONET IR-1

applications.

The optical subassembly consists of 2 parts,

the transmitter with an uncooled DFB laser in

a hermetic coaxial module, and the receiver

with a PD preamp in a hermetic coaxial

module and integrated circuits for reshaping

received optical signal.

incorporated, which allows users to interface

with two wire serial interface that displays

information on manufacturer, part number,

link, distance, and other parameters.

The Digital Diagnostic Monitoring interface is

incorporated, which can be monitored

These pins are the Transmitter ground connections.

They should be connected to a low impedance ground plane(0V).

9,10,

16

RX GND

TX Vcc

I

These pins are the Receiver ground connections.

They should be connected to a low impedance ground plane(0V).

This is the power supply pin for the Transceiver part.

It should be connected to +3.3V.

Recommended power supply decoupling. (See Figure 8)

15

RX Vcc

I

This is the power supply pin for the Receiver part.

It should be connected to +3.3V.

Recommended power supply decoupling. (See Figure 8)

This data input pin modulates the laser diode. When the TD+ input is

asserted, the laser diode is turned on.

18,19

TD+ / TD-

They are internally AC-coupled into an equivalent load of RI differential, as

shown in Figure 8.

3

TX_DISABLE

RD+ / RD-

I

Active high TTL input, with internal 7.4k ohm pull-up resistor to Vcc.

Asserting the transmitter disable will deactivate the laser within the assert

time. Table 1 indicates the timing of TX_DISABLE.

Received Data Out and Inverted Received Data Out are differential serial

output from the receiver.

12,13

O

These are AC-coupled 100 ohm differential lines which should be terminated

with a 100 ohm (differential) at the user SERDES, as shown in Figure 8. AC

coupling is done inside the module and is thus not required on the host board.

Active high open collector/drain output which indicates a loss-of-signal

condition (LOS). When the average optical power received by the module is

below the Assert Level, RX_LOS is indicated.

Table 1 indicates the timing of RX_LOS. RX_LOS requires a 4.7k to 10k

ohm pull-up resistor external to the module, i.e., in the host system Host_Vcc,

as shown in Figure 8.

The pull-up voltage is between 2.0 V and VccR(VccT) + 0.3 V.

Active high open collector/drain output which indicates a fault in the module.

This can be failure of the laser diode. Under this conditions, TX_FAULT will

activate and be latched. And then the laser will be deactivated within the

assert time.

RX_LOS

O

TX_FAULT

TX_FAULT also requires a 4.7k to 10k ohm pull-up resistor externally, i.e. in

the host system Host_Vcc, as shown in Figure 8.

The pull-up voltage is between 2.0 V and VccT(VccR) +0.3V.

It can be reset by toggling TX_DISABLE high for at least t_reset.

See Figure 8 and Figure 5.

MOD_DEF[0:2]

-

This module has a serial ID function which provides information about the

transceiver’s capabilities, standard interfaces, manufacturer and other

information.

This function is provided via a two wire serial EEPROM interface.

MOD_DEF[0] is connected to ground inside the module.(LOW)

MOD_DEF[1] is the serial clock signal input.(SCL)

MOD_DEF[2] is the data output/input.(SDA)

The serial ID definitions are as given in the “SFP-MSA” standard.

See Figure 9.
