SECTION 1 FUNCTIONAL DESCRIPTION
The PLRXPL-VI-S24-22 850 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 fiber.
Transmitter
www..com
The transmitter converts 8B/10B encoded serial PECL or CML electrical data into serial optical data meeting the requirements of 100-M5/M6-SN-I, 200-M5/M6-SN-I Fibre Channel specifications and 1000BASE-SX Ethernet. 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 VccT. 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 seated and the transmitter is disabled. A logic "0" on this pin indicates normal operation.
Receiver
The receiver converts 8B/10B encoded serial optical data into serial PECL/CML electrical data. Receive data lines (RD+ & RD-) are internally AC coupled with 100 differential source impedance, and must be terminated with a 100 differential load. The receiver's bandwidth has been optimized for fully compliant operation ar 2.125, 1.25 and 1.063 Gbps line rates without the use of rate select. Rate select pin 7 has no effect. An open collector compatible Loss of Signal is provided. The LOS must be pulled high on the host board for proper operation. A logic "0" indicates that light has been detected at the input to the receiver (see Section 2.5 Optical characteristic, Loss of Signal Assert/Deassert Time on page 9). A logic "1" output indicates that insufficient light has been detected for proper operation. Power supply filtering is recommended for both the transmitter and receiver. Filtering should be placed on the host assembly as close to the Vcc pins as possible for optimal performance. Recommended "Application Schematics" are shown in Figure 2 on page 5.

Power supply filtering components should be placed as close to the Vcc pins of the host connector as possible for optimal performance. PECL driver and receiver will require biasing networks. Please consult application notes from suppliers of these components. CML I/O on the PHY are supported. MOD_DEF(2) and MOD_DEF(1) should be bi-directional open collector connections in order to implement serial ID (MOD_DEF[0,1,1]) PLRXPL-VI-S24-22 transceiver. R1 and R2 may be included in the output of the PHY. Check application notes of the IC in use. Transmission lines should be 100 differential traces. It is recommended that the termination resistor for the PECL Receiver (R3 + R4) be placed beyond the input pins of the PECL Receiver. Series Source Termination Resistors on the PECL Driver (R1+R2) should be placed as close to the driver output pins as possible

Specification notes 1. UI (Unit Interval): one UI is equal to one bit time. For example, 2.125 Gbits/s corresponds to a UI of 470.588ps. 2.For LOSA and LOSD definitions see Loss of Signal Assert/Deassert Level in Section 2.5 Optical characteristic on page 10. 3.When operating the transceiver at 1.0 - 1.3 Gbaud only, a slower input rise and fall time is acceptable. If it is planned to operate the module in the 1.0 - 2.12 Gbaud range, faster input rise and fall times are required. 4.Measured with stressed eye pattern as per FC-PI (Fibre Channel) and 1000BASE-SX using the worst case specifications. 5.All jitter measurements performed with worst case input jitter according to FC-PI and 1000BASE-SX. 6.Distances, shown in the "Link Length" table, are the distances specified in the Fibre Channel and Ethernet standards. "Link Length" distances are calculated for worst case fiber and transceiver characteristics based on the optical and electrical specifications shown in this document using techniques utilized in IEEE 802.3 (Gigabit Ethernet). In the nominal case, longer distances are achievable.

Reading the data
The information is accessed through the MOD_DEF(1), and MOD_DEF(2) connector pins of the module.The specification for this EEPROM (ATMEL AT24CO1A family) contains all the timing and addressing information required for accessing the data. The device address used to read the Serial ID data is 1010000X(A0h), and the address to read the diagnostic data is 1010001X(A2h) . Any other device addresses will be ignored. Refer to Table 3, Table 4, and Table 5 for information regarding addresses and data field descriptions MOD_DEF(0), pin 6 on the transceiver, is connected to Logic 0 (Ground) on the transceiver. MOD_DEF(1), pin 5 on the transceiver, is connected to the SCL pin of the EEPROM. MOD_DEF(2), pin 4 on the transceiver, is connected to the SDA pin of the EEPROM. The EEPROM WP pin is internally tied to ground with no external access, allowing write access to the customerwritable field(bytes 128-247 of address 1010001X). Note: address bytes 0-127 are not write protected and may cause diagnostic malfunctions if written over.

3.2 Package and handling instructions Process plug
The PLRXPL-VI-S24-22 is supplied with a dust cover. This plug protects the transceiver's optics during standard manufacturing processes by preventing contamination from air borne particles. Note: It is recommended that the dust cover remain in the transceiver whenever an optical fiber connector is not inserted. www..com
Recommended cleaning and de-greasing chemicals
Picolight recommends the use of methyl, isopropyl and isobutyl alcohols for cleaning. Do not use halogenated hydrocarbons (e.g. trichloroethane, ketones such as acetone, chloroform, ethyl acetate, MEK, methylene chloride, methylene dichloride, phenol, N-methylpyrolldone).
Flammability
The PLRXPL-VI-S24-22 housing is made of cast zinc and sheet metal.
3.3 ESD Discharge (ESD) Handling
Normal ESD precautions are required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from the packaging and handled only in an ESD protected environment utilizing standard grounded benches, floor mats, and wrist straps.
Test and operation
In most applications, the optical connector will protrude through the system chassis and be subjected to the same ESD environment as the system. Once properly installed in the system, this transceiver should meet and exceed common ESD testing practices and fulfill system ESD requirements. Typical of optical transceivers, this module's receiver contains a highly sensitive optical detector and amplifier which may become temporarily saturated during an ESD strike. This could result in a short burst of bit errors. Such an event might require that the application re-acquire synchronization at the higher layers (e.g. Serializer/ Deserializer chip).
3.4 Eye safety
The PLRXPL-VI-S24-22 is an international Class 1 laser product per IEC 825, and per CDRH, 21 CFR 1040 Laser Safety Requirements. The PLRXPL-VI-S24-22 is an eye safe device when operated within the limits of this specification. Operating this product in a manner inconsistent with intended usage and specification may result in hazardous radiation exposure.
