Descriptions

Baudcom’ BDTRP695S1SD-40, The
SFP-BIDI transceivers are high performance, cost effective modules supporting
dual data-rate of 2.5Gbps/2.125Gbps and 40km transmission distance with SMF. The
transceiver consists of three sections: a DFB laser transmitter, a PIN
photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control
unit. All modules satisfy class I laser safety requirements. The transceivers
are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further
information, please refer to SFP MSA.

General Operating
Characteristics

Electrical
Characteristics (TOP(C) = 0 to 70 ℃, TOP(I) =-40 to 85 ℃,VCC = 3.13 to 3.47 V)

.Notes:

1. TD+/- are internally AC coupled with 100Ω
differential termination inside the module.

2. Tx Fault and Rx LOS are open collector
outputs, which should be pulled up with 4.7k to 10kΩ resistors on the host
board. Pull up voltage between 2.0V and Vcc+0.3V.

3.RD+/- outputs are internally AC coupled, and
should be terminated with 100Ω (differential) at the user SERDES.

Notes:

1.Measured at 2.5Gb/s with PRBS 2 2^{23 – 1}NRZ test pattern.

2.Unfiltered, measured with a PRBS2^{23 – 1} test pattern @2.5Gb/s

3.Measured at 2.5Gb/s with PRBS 2^{23 – 1} NRZ test pattern for BER < 1×10^-12

Pin Defintion And
Functions

Notes:

1.When high, this output indicates a laser
fault of some kind. Low indicates normal operation. And should be pulled up
with a 4.7 – 10KΩ resistor on the host board.

2. TX disable is an input that is used to shut
down the transmitter optical output. It is pulled up within the module with a
4.7 – 10KΩ resistor. Its states are:

  Low (0
– 0.8V): Transmitter on              
(>0.8, < 2.0V): Undefined

  High
(2.0V~Vcc+0.3V): Transmitter Disabled  
Open: Transmitter Disabled

3.Mod-Def 0,1,2. These are the module
definition pins. They should be pulled up with a 4.7K – 10KΩ resistor on the
host board. The pull-up voltage shall be between 2.0V~Vcc+0.3V.

      
Mod-Def 0 has been grounded by the module to indicate that the module is
present

      
Mod-Def 1 is the clock line of two wire serial interface for serial ID

      
Mod-Def 2 is the data line of two wire serial interface for serial ID

4.When high, this output indicates loss of
signal (LOS). Low indicates normal operation.

5.RD+/-: These are the differential receiver
outputs. They are AC coupled 100Ω differential lines which should be terminated
with 100Ω (differential) at the user SERDES. The AC coupling is done inside the
module and is thus not required on the host board.

6. TD+/-: These are the differential transmitter
inputs. They are AC-coupled, differential lines with 100Ω differential termination
inside the module. The AC coupling is done inside the module and is thus not
required on the host board.

Digital Diagnostic
Specifications

TheBDTRP695S1SD-40 transceivers can be used in
host systems that require either internally or externally calibrated digital
diagnostics.

Notes:

1.When
Operating temp.=0~70 oC,the
range will be min=-5,Max=+75

2. The
accuracy of the Tx bias current is 10% of the actual current from the laser
driver to the laser

3. Internal/ External Calibration
compatible.
