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.
