Section 1
The PLRXPL-VE-SG4-38 850 nm VCSEL Gigabit Transceiver is designed to trans-
mit and receive 8B/10B or 64B/66B encoded serial optical data over 50/125 µm
or 62.5/125 µm multimode optical fiber. This transceiver is RoHS-compliant per
Directive 2002/95/EC.
Transmitter
The transmitter converts 8B/10B or 64B/66B encoded serial PECL or CML electri-
cal data into serial optical data meeting the requirements of 100-M5/M6-SN-I,
200-M5/M6-SN-I, 400-M5/M6-SN-I Fibre Channel and 1000Base-SX Ethernet
specifications. Transmit data lines (TD+ & TD-) are internally AC coupled with
100 Ω differential termination.
An open collector compatible Transmit Disable (Tx_Dis) is provided. This pin is
internally terminated with a 10 kΩ resistor to Vcc
on this pin will disable the laser from transmitting. A logic “0” on this pin provides
normal operation.
The transmitter has an internal PIN monitor diode that is used to ensure constant
optical power output across supply voltage and temperature variations.
An open collector compatible Transmit Fault (TFault) is provided. The Transmit Fault
signal must be pulled high on the host board for proper operation. A logic “1” output
from this pin indicates that a transmitter fault has occurred, or the part is not fully seat-
ed and the transmitter is disabled. A logic “0” on this pin indicates normal operation.
The extinction ratio of the transmitter is automatically increased to meet the re-
quirements of 1000BASE-SX Ethernet specifications when the Rate Select pin and
software bit are set to “low”.
Receiver
The receiver converts 8B/10B or 64B/66B encoded serial optical data into serial
PECL/CML electrical data. Receive data lines (RD+ and RD-) are internally AC
coupled with 100 Ω differential source impedance, and must be terminated with
a 100 Ω differential load.
Rate select, pin 7, switches the receiver bandwith enabling superior performance
at 4.25 Gbps, 2.125 Gbps, 1.25 and 1.0625 Gbps line rates. When rate-select is set
“high” (4.25/2.125 Gbps mode) the receiver bandwidth is not compliant to the
maximum receiver bandwidth specified under 100-M5/M6-SN-I.
