ROHS-COMPLIANT 4.25 GBPS 850 NM ESFP TRANSCEIVERS;
EXTENDED/INDUSTRIAL TEMPERATURE & VOLTAGE
The PLRXPL-VE-SG4-38/PLRXPL-VI-SG4-38 850 nm VCSEL Gigabit Transceiver
is designed to transmit and receive 8B/10B encoded serial optical data over 50/125
m or 62.5/125 m multimode optical ber. This transceiver is lead-free and
RoHS-compliant per Directive 2002/95/EC.
Transmitter
The transmitter converts 8B/10B encoded serial PECL or CML electrical data into se-
rial 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 specications. Transmit
data lines (TD+ & TD-) are internally AC coupled with 100 differential termination.
An open collector compatible Transmit Disable (Tx_Dis) is provided. This pin is
internally terminated with a 10 k resistor to Vcc
T. A logic “1,” or no connection
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 specications when the Rate Select pin and
software bit are set to “l(fā)ow”.
Receiver
The receiver converts 8B/10B encoded serial optical data into serial PECL/CML
electrical data. Receive data lines (RD+ and RD-) are internally AC coupled with 100
differential source impedance, and must be terminated with a 100 differential load.
Rate select, pin 7, switches the receiver bandwith enabling superior performance at
4.25 Gbps, 2.125 Gbps, 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 specied under 100-M5/M6-SN-I.
