Product description
This 850 nm VCSEL 10Gigabit SFP+ transceiver is designed to transmit and receive optical data over 50/125μm or 62.5/125μm multimode optical fiber.
The SFP+ SR module electrical interface is compliant to SFI electrical specifications. The transmitter
input and receiver output impedance is 100 Ohms differential. Data lines are internally AC coupled.
The module provides differential termination and reduce differential to common mode conversion for quality signal termination and low EMI. SFI typically operates over 200 mm of improved FR4 material or up to about 150mmof standard FR4 with one connector.
The transmitter converts 10Gbit/s serial PECL or CML electrical data into serial optical data compliant with the 10GBASE-SR standard. An open collector compatible Transmit Disable (Tx_Dis) is provided.
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 automatic power control loop (APC) to ensure constant optical power output across supply voltage and temperature variations. An open collector compatible Transmit Fault (TFault) is provided. TX_Fault is a module output contact that when high, indicates that the module transmitter has detected a fault condition related to laser operation or safety. The TX_Fault output contact is an open drain/collector and shall be pulled up to the Vcc_Host in the host with a resistor in the range 4.7-10 kΩ. TX_Disable is a module input contact. When TX_Disable is asserted high or left open, the SFP+ module transmitter output shall be turned off.
This contact shall be pulled up to VccT with a 4.7 kΩ to 10 kΩ resistor
The receiver converts 10Gbit/s serial optical data into serial PECL/CML electrical data. An open collector compatible Loss of Signal is provided. Rx_LOS when high indicates an optical signal level below that specified in the relevant standard. The Rx_LOS contact is an open drain/collector output and shall be pulled up to Vcc_Host in the host with a resistor in the range 4.7-10 kΩ, or with an active termination. Power supply filtering is recommended for both the transmitter and receiver. The Rx_LOS signal is intended as a preliminary indication to the system in which the SFP+ is installed that the received signal strength is below the specified range. Such an indication typically points to non-installed cables, broken cables, or a disabled, failing or a powered off transmitter at the far end of the cable.

Digital Diagnostic Functions
The ES85X-3LCD04 transceivers support the 2-wire serial communication protocol as defined in the SFP MSA1.
The standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities,
standard interfaces, manufacturer, and other information.
Additionally, the SFP+ transceivers provide a unique enhanced digital diagnostic monitoring interface, which allows
real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical
power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning
flags, which alerts end-users when particular operating parameters are outside of a factory set normal range.
The SFP MSA defines a 256-byte memory map in EEPROM that is accessible over a 2-wire serial interface at the 8 bit
address 1010000X (A0h). The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so
the originally defined serial ID memory map remains unchanged.
The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller
(DDTC) inside the transceiver, which is accessed through a 2-wire serial interface.
When the serial protocol is activated,
the serial clock signal (SCL, Mod Def 1) is generated by the host. The positive edge clocks data into the SFP transceiver
into those segments of the E2PROM that are not write-protected. The negative edge clocks data from the SFP transceiver.
The serial data signal (SDA, Mod Def 2) is bi-directional for serial data transfer. The host uses SDA in conjunction with SCL
to mark the start and end of serial protocol activation. The memories are organized as a series of 8-bit data words that can
be addressed individually or sequentially.
