To avoid electrostatic damage, handling cautions similar those used for MOS devices must be observed. May 2000 DESCRIPTION strobed. Inputs 1 to 11 are routed before inputs 12 to 22. 4B words are then fed through eleven separate 4B/5B encoders to form the signals to be transmitted over the optical interface. Coding is based on the running disparity of previously transmitted output data. With a running disparity=>0, either more High than Low levels or an equal number of Highs and Lows have been transmitted. The next output nibble will be inverted if High levels again dominate; otherwise it will be sent without inversion. With a running disparity <0, more Low than High levels have been transmitted. The next output nibble will be inverted if Low levels again dominate; otherwise it will be sent uninverted. To indicate whether a nibble has been inverted, an inversion bit is added, thus forming a 5B word (High, if transmitted nibble is uninverted; Low, if transmitted nibble is inverted). It is placed in front of the nibble (at the beginning of the 5B word) and immediately follows the FRAME transition. FRAME signal transitions delimit 5B words. Each 5B word contains the inversion bit and the nibble (inverted or non-inverted) mounted from two input data strobe cycles. The 5B words and FRAME signal are the signals transmitted over the optical interface. The pulse lengths of the 5B word and the frame signal is twice the pulse length of the electrical input signal. PAROLI is a parallel optical link for high-speed data transmission. A complete PAROLI system consists of a transmitter module, a 12-channel fiber optic cable, and a receiver module. Transmitter V23814-K1306-M230 The PAROLI transmitter module converts parallel electrical input signals (data and clock) into parallel optical output signals. Figure 1. Transmitter block diagram Electrical Inputs 22 Data Inputs Clock Input Optical Outputs 22 Input Stage 11 Multiplexer Laser Encoder Frame Driver PLL 11 11 VCSEL Array Data Fibers Frame Fiber #1 Module LE -LE Up Laser Laser Enable Controller Up -RESET CLK_SEL Example All electrical data and clock inputs are LVDS compatible. The module also features several LVCMOS compatible control inputs and outputs, which are described in the Transmitter Pin Description (table starting on page 5). The module features multiplexing and encoding of 22 electrical data input channels to 11 optical data output channels. The input data are serialized by 2 to 1 multiplexers which results in a reduced data rate at the electrical interface. The multiplexed data are encoded (4B/5B encoding) to achieve DC-balanced signals at the input of the laser driver. The electrical input clock signal is used to control an integrated PLL circuit, which generates internal clock signals for encoding and multiplexing. The PLL circuit also generates a frame signal for the optical interface, which is transmitted over a separate fiber. Transmission delay of the PAROLI system is at a maximum of 4 strobe cycles + 3 ns for the transmitter, 3 strobe cycles + 3 ns for the receiver, and approximately 5 ns per meter for the fiber optic cable. To transmit electrical data at the maximum data rate of 500 Mbit/s per channel the corresponding clock signal (square 0101 pattern) has a frequency of 250 MHz in SCI mode or 500 MHz in STROBE mode. The FRAME signal with a corresponding frequency of 125 MHz is transmitted via fiber #1. The data rate of the optical signal at the Transmitter output is 1.25 Gbit/s in each of the fibers #2 to #12. Clocking Modes Caution The transmitter can be operated in one of two input clocking modes: Strobe mode or SCI mode. The mode is selected via CLK_SEL input. In Strobe mode, the rising edges of the noninverted clock signal are centered over the data bits. In SCI mode, High/Low transitions of clock and data signals coincide. In SCI mode, the transmitter‘s electrical interface complies with the SCI standard. See Timing diagram Figure 5 on page 4. Do not stare into beam or view directly with optical instruments. The use of optical instruments with this product will increase eye hazard. LASER SAFETY The transmitter of the DC coupled Parallel Optical Link (PAROLI) is an FDA Class 1 laser product. It complies with FDA regulations 21 CFR 1040.10 and 1040.11. The transmitter is an IEC Class 3A laser product as defined by IEC 60825-1. To avoid possible exposure to hazardous levels of invisible radiation, do not exceed maximum ratings. The PAROLI module must be operated under the specified operating conditions (supply voltage between 3.0 V and 3.6 V, case temperature between 0°C and 80°C) under all circumstances to ensure laser safety. Note Any modification of the module will be considered an act of “manufacturing,” and will require, under law, recertification of the product under FDA (21 CFR 1040.10 (i)). Figure 2. Laser emission Multiplexing and Encoding The electrical input data are strobed into the input register with the internal clock signal generated by the PLL and then multiplexed 2:1. Input channels 1 to 11 are grouped with input channels 12 to 22, i.e. data inputs 1 and 12 feed optical data output 1; data inputs 2 and 13 feed optical data output 2, etc. Four data bits read from two input channels during two strobe cycles form 4B words. Inside the 4B word, data from the lower inputs (1 to 11) is transmitted first, i.e. after input data are Laser aperture and beam Fiber Optics V23814/15-K1306-M230 Parallel Optical Link: PAROLI® Tx/Rx DC 2 TECHNICAL DATA The electro-optical characteristics described in the following tables are valid only for operation under the recommended operating conditions.

Fiber Optics V23814/15-K1306-M230 Parallel Optical Link: PAROLI® Tx/Rx DC 6 DESCRIPTION grouped with output channels 12 to 22, i.e. optical data input 1 feeds electrical data outputs 1 and 12; optical data input 2 feeds electrical data outputs 2 and 13, etc. Demultiplexing of a 4B word (with bits #1...#4) takes two data output cycles. During the first cycle, bit #1 is presented at the lower data output (1...11) and bit #2 at the higher data output (12...22). During the second cycle, bits #3 and #4 are presented at the lower and higher outputs, respectively. (Example: Of the 4B word from optical data channel 1, bit #1 is presented at corresponding lower data output 1 and bit #2 is presented at corresponding higher data output 12.) The demultiplexed data bits are presented as 22 parallel outputs together with the output clock signal, the characteristics of which depend on the clocking mode. (See Clocking Modes above.) Receiver V23815-K1306-M230 The PAROLI receiver module converts parallel optical input signals (data and frame) into parallel electrical output signals. Figure 8.

All electrical data and clock outputs are LVDS compatible. The module also features several LVCMOS compatible control inputs and outputs, which are described in the Receiver Pin Description (table starting on page 10). The module features demultiplexing and decoding of 11 optical data input channels to 22 electrical data output channels. The frame signal is used to control an integrated PLL circuit, which generates internal clock signals for decoding and demultiplexing. The PLL circuit also generates a clock signal at the Receiver output. Transmission delay of the PAROLI system is at a maximum of 4 strobe cycles + 3 ns for the transmitter, 3 strobe cycles + 3 ns for the receiver, and approximately 5 ns per meter for the fiber optic cable. If OE is at a high level or left open during start-up, clock output will start running immediately after release of -RESET. Clock frequency will drift upwards to the operating frequency established by FRAME input when FRAME_DET indicates sufficient input signal level. After PLL has locked (indicated by LOCK_DET high level) data outputs are also enabled. OE can be used for complete LVDS switch-off whenever clock drift during start-up is critical. Clocking Modes The receiver can be operated in one of two output clocking modes: Strobe mode or SCI mode. The mode is selected via CLK_SEL input. In Strobe mode, the rising edges of the noninverted clock signal are centered over the data bits. In SCI mode, High/Low transitions of clock and data signals coincide. In SCI mode the electrical interface complies with the SCI standard. See Timing diagram Figure 10. Decoding and Demultiplexing The input data received from the optical interface are strobed into the input register with the PLL generated internal clock signal. The data are read in relation to FRAME input. The input frequency expected at FRAME is one fifth of square input data frequency, as FRAME transitions indicate 5B word boundaries. FRAME input is expected to change levels simultaneously with data transitions. All eleven input data channels are fed through individual 5B/4B decoders. Decoding is based on an inversion bit which is received at the first position of a 5B word. This bit determines whether the nibble received at bit positions 2, 3, 4 and 5 has to be inverted. An inversion bit High level indicates a nibble which was transmitted uninverted, i.e. this 4B nibble will be directly forwarded to the demultiplexer. If the inversion bit received is Low, the corresponding nibble will be inverted by the decoder before it is demultiplexed. The 4B words from the decoders are then demultiplexed 1:2 to electrical output data channels.

Figure 13 shows the mechanical dimensions of the PAROLI transmitter and receiver modules and Figures 14 to 16 give the dimensions of the holes and solder pads on a customer PCB that are necessary to mount the modules on this PCB. Keeping the tolerances for the PCB given in Figures 14 to 16 is required to properly attach the PAROLI transmitter and receiver module to the PCB. Attachment to the customer PCB should be done with four M2 screws torqued to 0.25 Nm + 0.05 Nm (see Figure 13, cross section B-B). The screw length a should be 3 to 4 mm plus the thickness b of the customer PCB. Special care must be taken to remove residues from the soldering and washing process which can impact the mechanical function. Avoid the use of aggressive organic solvents like ketones, ethers, etc. Consult the supplier of the PAROLI modules and the supplier of the solder paste and flux for recommended cleaning solvents. The following common cleaning solvents will not affect the module: deionized water, ethanol, and isopropyl alcohol. Air-drying is recommended to a maximum temperature of 140°C. Do not use ultrasonics. During soldering, heat must be applied to the leads only, to ensure that the case temperature never exceeds 140°C. The module must be mounted with a hot-air or hot-bar soldering process using a SnPb solder type, e.g. Sn62Pb36Ag2, in accordance with ISO 9435.
