To enable the laser, an LVTTL low input must be applied. Leave pin unconnected if feature not required. SD LVTTL output for V23818-C18-L4x. LVPECL output for V23818-C18-L3x/L436. A logical high output indicates normal optical input levels to the receiver. Low optical input levels at the receiver result in a low output. Signal Detect can be used to determine a definite optical link failure; break in fiber, unplugging of a connector, faulty laser source. However it is not a detection of a bad link due to data-related errors. MS Mounting studs are provided for transceiver mechanical attachment to the circuit board. They also provide an optional connection of the transceiver to the equipment chassis ground. The holes in the circuit board must be tied to chassis ground. HL Housing leads are provided for additional signal grounding. The holes in the circuit board must be included and tied to signal ground.

Description Description This data sheet describes the Infineon single mode ATM transceiver, which complies with the ATM Forum's Network Compatible ATM for Local Network Applications document and ANSI's Broadband ISDN - Customer Installation Interfaces, Physical Media Dependent Specification, T1E1.2, compliant to SONET OC-3, IR-1 (Telcordia GR-253-CORE) and SDH STM-1/S-1.1 (ITU-T G.957). This transceiver is also suitable for multirate applications. The performance at lower datarates may vary from application to application and is link dependent. Refer to Infineon Application Note 97 for more information. ATM was developed to facilitate solutions in multimedia applications and real time transmission. The data rate is scalable, and the ATM protocol is the basis of the broadband public networks being standardized in the International Telecommunications Union (ITU), the former International Telegraph and Telephone Consultative Committee (CCITT). ATM can also be used in local private applications. The Infineon single mode ATM transceiver is a single unit comprised of a transmitter, a receiver, and an LC receptacle. This design frees the customer from many alignment and PC board layout concerns. The module is designed for low cost LAN and WAN applications. It can be used as the network end device interface in workstations, servers, and storage devices, and in a broad range of network devices such as bridges, routers, and intelligent hubs, as well as local and wide area ATM switches. This transceiver operates at up to 155.520 Mbit/s from a single power supply (+3.3 V). The full differential data inputs and outputs are LVPECL compatible.

Functional Diagram
The receiver component converts the optical serial data into LVPECL compatible electrical data (RD+ and RD-). The Signal Detect (SD, active high) shows whether an optical signal is present. The transmitter converts LVPECL compatible electrical serial data (TD+ and TD-) into optical serial data. The transmitter contains a laser driver circuit that drives the modulation and bias current of the laser diode. The currents are controlled by a power control circuit to guarantee constant output power of the laser over temperature and aging. The power control uses the output of the monitor PIN diode (mechanically built into the laser coupling unit) as a controlling signal, to prevent the laser power from exceeding the operating limits. Single fault condition is ensured by means of an integrated automatic shutdown circuit that disables the laser when it detects laser fault to guarantee the laser eye safety. The transceiver contains a supervisory circuit to control the power supply. This circuit makes an internal reset signal whenever the supply voltage (VCCt) drops below the reset threshold (VTH). It keeps the reset signal active for at least 140 milliseconds after the voltage has risen above the reset threshold. During this time the laser is inactive. A high signal on TDis enables the transmitter. If TDis is low or not connected the transmitter is not affected.

Jitter The transceiver is specified to meet the SONET/SDH Jitter performance as outlined in ITU-T G.958 and Telcordia GR-253. Jitter Generation is defined as the amount of jitter that is generated by the transceiver. The Jitter Generation specifications are referenced to the optical OC-3 signals. If no or minimum jitter is applied to the electrical inputs of the transmitter, then Jitter Generation can simply be defined as the amount of jitter on the Tx optical output. The SONET specifications for Jitter Generation are 0.01 UI RMS, maximum and 0.1 UI pk-pk, maximum. For SDH, 10 mUI RMS, maximum. Both are measured with a 12 kHz 1.3 MHz filter in line. A UI is a Unit Interval, which is equivalent to one bit slot. At OC-3, the bit slot is 6.4 ns, so the Jitter Generation specification translates to 64 ps RMS, max. and 640 ps pk-pk, max.

Minimum average optical power at which the BER is less than 1x10-10. Measured with a 223-1 NRZ PRBS. Worst case receiver sensitivity at 25C is -31 dBm (beginning of life). An increase in optical power of data signal above the specified level will cause the Signal Detect to switch from a low state to a high state (high active output). A decrease in optical power of data signal below the specified level will cause the Signal Detect to switch from a high state to a low state. Load is 100 differential. Measured under DC conditions at 25C. For dynamic measurements a tolerance of 50 mV should be added. Only for V23818-C18-L3x/L436. Only for V23818-C18-L4x.

EMI-Recommendations EMI-Recommendations To avoid electromagnetic radiation exceeding the required limits please take note of the following recommendations. When high speed components are found on a PCB (multiplexers, clock recoveries etc.) any opening of the chassis may produce radiation also at chassis slots other than that of the device itself. Thus every mechanical opening or aperture should be as small as possible. On the board itself every data connection should be an impedance matched line (e.g. strip line, coplanar strip line). Data, Datanot should be routed symmetrically, vias should be avoided. A terminating resistor of 100 should be placed at the end of each matched line. An alternative termination can be provided with a 50 resistor at each (D, Dn). In DC coupled systems a thevenin equivalent 50 resistance can be achieved as follows: for 3.3 V: 125 to VCC and 82 to VEE, for 5 V: 82 to VCC and 125 to VEE at Data and Datanot. Please consider whether there is an internal termination inside an IC or a transceiver. In certain cases signal GND is the most harmful source of radiation. Connecting chassis GND and signal GND at the plate/ bezel/ chassis rear e.g. by means of a fiber optic transceiver may result in a large amount of radiation. Even a capacitive coupling between signal GND and chassis may be harmful if it is too close to an opening or an aperture. If a separation of signal GND and chassis GND is not planned, it is strongly recommended to provide a proper contact between signal GND and chassis GND at every location where possible. This concept is designed to avoid hotspots. Hotspots are places of highest radiation which could be generated if only a few connections between signal and chassis GND exist. Compensation currents would concentrate at these connections, causing radiation. By use of Gigabit switching components in a design, the return path of the RF current must also be considered. Thus a split GND plane of Tx and Rx portion may result in severe EMI problems. A recommendation is to connect the housing leads to signal GND. However, in certain applications it may improve EMI performance by connecting them to chassis GND. The cutout should be sized so that all contact springs make good contact with the face plate. Please consider that the PCB may behave like a waveguide. With an r of 4, the wavelength of the harmonics inside the PCB will be half of that in free space. In this scenario even the smallest PCBs may have unexpected resonances.
