Detector (ED). This PAM4 BERT supports 400GbE testing when these modules are installed in the Anritsu Signal Quality Analyzer-R MP1900A series to implement a bit- error-rate test solution with best-in-class signal level quality and excellent Rx sensitivity for next-generation broadband communication systems. Due to the expansion of next-generation 5G mobile communications and Cloud services, data traffic volumes are expected to increase. To manage this demand, infrastructure operators, such as data centers, are investigating the improvements to speed in PAM4 and multilane communications systems. Now 400GbE speeds are being deployed using either the 26.5625Gbaud PAM4 x 8 lanes or 53.125- Gbaud PAM4 x 4 lanes methods. To meet this technical demand, Anritsu has developed the released 64-Gbaud PAM4 PPG with ‘best-in-class’ signal level quality and the 32-Gbaud PAM4 ED with excellent Rx sensitivity performance to support evaluation of equipment and devices for high-speed, large-capacity transmissions. When using the PAM4 method to encode data as four amplitude levels, the gap between signal levels is one- third compared to the NRZ method, which reduces the unit time per symbol at higher baud rates, emphasizing the importance of signal quality in achieving high-speed transmissions. However, the degraded signal quality caused by crosstalk and noise resulting from use of multiple lanes and high- density circuit design increases the need for evaluation of minimum Rx sensitivity using stress-test signals. The Signal Quality Analyzer-R MP1900A is a leading bit error rate tester for the over 400G market and supports generation of high-speed signals as well as analysis of signal performance. The new PPG for PAM4 signals up to 64 Gbaud has the world’s best Tr/Tf (20% to 80%) time of 8.5 ps (typ.) and Intrinsic Jitter of 170 fs (typ.). Moreover, the multichannel function can be expanded up to 4 channels, and the integrated Emphasis function corrects signals degraded by transmission path loss. The 32-Gbaud PAM4 ED module has a high sensitivity performance of 23 mV (typ.) and supports installation of a clock recovery function required for Rx sensitivity evaluation, as well as PAM4 symbol error measurements. As a result, the true performance of 400GbE optical modules and devices can now be tested within an adequate margin, satisfying the specifications. This means you can now avoid difficulties in achieving an

Ams releases industry’sslimmestproximity/ color sensor module for bezel-less smartphone designs ams, a leading worldwide supplier of high performance sensor solutions, today introduced a 1.44mm-wide fully integrated color/ambient light/proximity sensor module which has the super-slim package footprint required by the latest narrow-bezel mobile phone industrial designs. It will enable manufacturers to better optimize automatic disabling of smartphone touch screens during calls and the adjustment of screen brightness to ambient conditions for more comfortable and lower- energy smartphone use. By using ams’s new TMD3702VC three-in-one integrated module supplied in a 1.44mm x 2.84mm x 0.65mm package in place of earlier modules that have a wider footprint, smartphone manufacturers can implement designs that have a thinner bezel, to give a greater ratio of display area to body size, while retaining important infrared proximity and light-sensing functions. The module integrates an IR emitter, IR detector, four color-sensing channels and optical filters. Sophisticated new optical packaging technology and design techniques developed by ams for the TMD3702VC have enabled it to produce class-leading performance. The proximity sensor’s Vertical Cavity Surface Emitting Laser (VCSEL) Class 1 Eye Safe 940nm emitter is more optically efficient than the LED emitters found in competing devices. This keeps average Active mode power consumption of the
