3 General 
PT7323 transceiver is a high performance, cost effective module for serial optical data communication 
application.

3.1 Transmitter Section 
Transmitter is designed for single mode fiber and operates at a nominal wavelength of 1310nm. The 
transmitter module uses a MQW FP laser diode and full IEC825 and CDRH class 1 eye safety. The 
output optical power can be disabled via the single TxDis pin. Logic LVTTL HIGH level disables the 
transmitter. It contains APC function, temperature compensation circuit, PECL data inputs, LVTTL TxDis 
input interface. 
3.2 Receiver Section 
The receiver section uses a hermetic packaged PINTIA (InGaAs PIN and trans-impendence amplifier) 
and a limiting amplifier. Which transforms input optical power to optical current through PIN PD. And the 
optical current is transformed to voltage signal bytrans-impendence amplifier. Differential DATA and 
/DATA LVPECL data signal that is open emitter output is produced by limiting amplifier and voltage 
signal that is through limiting amplifier and filter. The receiver signal detect monitors input optical signal. 
When the optical power is not enough to support module operating normally, SD pin will beat LVPECL 
logic level 0 and signal detect appears. The PINTIA is ac coupled to limiting amplifier through a low pass 
filter. The LPF are enough to pass the signal from 5Mb/s to 200Mb/s without significant distortion or 
performance penalty.  
3.3  Power Supply Filtering and Ground Planes 
It is important to exercise care in circuit board layout to achieve optimum performance from these 
transceivers. It is further recommended that a continuous ground plane be provided in the circuit board 
directly under the transceiver to provide a low inductance ground for signal return current. 
3.4  Electromagnetic Interference (EMI) 
One of a circuit board designer’s foremost concerns is the control of electromagnetic equipment. 
Success in controlling generated Electromagnetic Interference (EMI) enables the designer to pass a 
governmental agency’s EMI regulatory standard and more importantly, it reduces the possibility of 
interference to neighboring equipment. PT7323 provides excellent EMI performance. PHOTON LC 
transceiver use forward and backward shields, which obturates the interstice of LC module effectually, 
and improves EMI performance. 
3.5 Application Note 
There are a few fundamental guidelines to follow when designing the PT7323 circuit interface. On the 
board, every data connection should be an impedance match. The data inputs and outputs lines should 
be treaded as 50ohm microstrip line, and vias should be avoided. The matching resistor should be 
placed at the end of each matched line. The PT7323 is high frequency, high bandwidth circuits. To 
ensure stability, use good high frequency layout techniques, filter voltage circuit, and keep ground 
connections short. 
4 Performance Specifications 
Caution:stresses in excess of the absolute maximum ratings can cause catastrophic damage to the 
device, all parameters having values within the recommended operating conditions.
