13th MOST Interconnectivity Conference 2012 Developed Product AFBR-1150/AFBR-2150 AFBR-1150 Transmitter: driver IC and LED with 650 nm, sleepand wake-up-function, differential LVDS input stage AFBR-2150 Receiver: photodiode and IC with preamp, post amp, sleep - and wake-up-function, differential LVDS output stage Features: 7 pin sidelooker package 3.3V supply voltages Temperature range -40 to 95degC Compliant to MOST150 ophy Automotive Physical Layer Sub-Specification Fully RoHS compliant
Time schedule MOST150 FOTs Start of project in 2006 Decision for Sidelooker in 2007 Product release in 2009 First supplier with released products on the market RELNETyX release in Jan 2010 Product ramp up in 2012 First introduction of MOST150 in Audi A3 in 2012 Page 10
One of the key challenges of MOST150 development was the extensive characterization and validation. Page 11
Very Extensive Receiver Characterization Sample size: 3 x 30 devices (from 3 different lots) Conditions 3 temperatures 3 supply voltages 10 optical input powers Each Rx was measured at 90 different conditions Data Rate 294.912 MBd Measuerements with MOST Stress Pattern Additional w.c. jitter measurements with FOT specific w.c. jittering MOST Stress Pattern Parameters: Rise and fall time, Differential output voltage, Jitter values (Total Jitter, Transferred Jitter), Current consumption FPM and LPM, Status VOH and VOL => resulted in 89 100 measurement values for the Rx only (without w.c. jitter measurements and power on/off ) Page 12
13th MOST Interconnectivity Conference 2012 Measurement results Receiver Eye Diagrams -40degC, -22dBm -40degC, -23.5dBm -40degC, -25dBm 95degC, -22dBm 95degC, -23.5dBm 95degC, -25dBm The Avago MOST150 Receiver shows excellent performance across temperature and optical input power. The eyemask is even met at -25dBm!

Worst Case Performance Testing All tests regarding signal integrity were performed using the MOST150 stress pattern The pattern is about 32kbits long and reflects a worst case scenario regarding the data sequence. SP2 (optical) clean SP4 (electrical) This pattern does not yet reflect the actual worst case input signal. This can only be achieved by applying worst case signals to SP1 or SP3 Since no particular eye mask is specified for SP3, a worst case SP2 signal has to be generated and in addition, a worst case optical fiber transmission has to be regarded. DCD RJ/DDJ DUT RX Page 15
Worst Case Input Signals Overshoot has no impact to the Rx signal integrity Duty Cycle Distortion has almost no impact to the Rx signal integrity Slow edges have only a minor impact to the Rx signal integrity We found that a mixture of RJ and especially DDJ has the highest impact on signal integrity SP4 Total Jitter 0.600 0.500 0.400 0.300 0.200 0.100 0.000 0.000 0.100 0.200 0.300 0.400 SP2 Total Jitter clean slow edges DCD RJ+DDJ OS, OS+DCD HSL SP2 HSL SP4 Page 16
Rx Total Jitter JT J [UI] 0.55 0.5 0.4 0.3 0.2 0.1-23.5 Feldvariable: VCC 3.13 3.46-22.0-20.0-17.0-14.0-11.0-8.0-5.0-2.0 JT [UI] T = 95-23.5-22.0-20.0-17.0-14.0-11.0-8.0-5.0 Graphs show the Total Jitter across the optical input power at 95 C (worst case temperature), grouped by power supply voltage Rx shows excellent jitter values even for low optical input powers close to the sensitivity limit 0.55 power 3.30-2.0 0.5 0.4 0.3 0.2 0.1 Page 17
High Temperature Operation Life Test (HTOL) Stress Conditions: Temperature: 95 C Bias: 3,3V 3 x lots, each lot 77 samples Graph shows data of one lot Normalized to 100% at 0h => Very stable optical performance across life time. No degradation of LED! Page 18
13th MOST Interconnectivity Conference 2012 Reflow Soldering Capabilities Avago was first to market with reflow solderable device. Release date of MOST25 was 2010 Pin in paste technology Reflow soldering is in accordance with JEDEC standard J-STD-020D Reflow devices are more robust because of: - Special mold compound - Optimized leadframe geometry - Improved manufacturing processes Also MOST150 was now improved and qualified. All qualification tests have been passed. Page 19
