Maxim Autonomous Driving Safety Systems
Maxim and NVIDIA have collaborated to support a Level 5 full-autonomy driving system, the NVIDIA DRIVE Pegasus platform, as well as a Level 4 driving system, NVIDIA DRIVE Xavier. Maxim's Automotive Safety Integrity Level (ASIL) systems and analog integration (which include gigabit multimedia serial link serializer and deserializer technology), as well as a power monitoring device, provide the foundation needed to meet functional safety requirements for NVIDIA's autonomous driving platform.
The 6Gbps GMSL SerDes technology supports the data rate, interconnect and data integrity requirements of future automotive infotainment, Advanced Driver Assistance Systems (ADAS) and autonomous driving. This technology also provides the relevant safety features needed to build autonomous driving systems such as DRIVE Pegasus.

Pasternack RF Attenuators
Pasternack has released a line of attenuators for quick mating and easy installation. Typical applications include DAS systems, remote radio heads (RRHs), base stations and antennas. The 23 quick connect attenuators are available with QMA, QN or 4.3-10 connectors. These RF attenuators support operating frequency ranges from DC to 6GHz. In addition, they provide attenuation values from 0 to 20dB and VSWR as low as 1.15:1.
The 4.3-10 attenuator models have a maximum power handling of up to 15W with low PIM performance. They eliminate the need for wrench or torque for coupling and are easy to screw on, allowing for hand-tightening. The QMA and QN models are constructed of brass tri-metal, while the 4.3-10 attenuators are made of anodized aluminum. All attenuator models meet IP67 and ingress protection rating requirements.
Information on pricing and availability can be found on Pasternack’s website.
Samsung Z-SSD Storage
Samsung has launched an 800-gigabyte solid-state storage drive—the SZ985 Z-SSD—intended for various enterprise applications, including supercomputing for AI analysis.The single-port, four-lane Z-SSD features Z-NAND chips that provide 10 times higher cell read performance than 3-bit V-NAND chips, along with 1.5GB LPDDR4 DRAM.
The Z-SSD supplies up to 30 drive writes per day for five years, or a total of 42 petabytes. That translates into storing a total of about 8.4 million 5GB-equivalent HD movies over a five-year period. The Z-SSD’s durability is also underscored by a mean time between failures of 2million hours.

Synopsys Arm Verification IP and Test Suite
Synopsys has announced the availability of its Verification IP (VIP) and source code Test Suite for Arm AMBA ACE5 (AXI Coherency Extensions) and AXI5.AXI5 and ACE5 add features for atomic operations to improve the performance and data check and poisoning to identify data corruption. ACE 5 and AXI5 also include low-power wake-up signals to provide a single, glitch-free indication that activity on the interface is required.
In addition, ACE5 has added support for cache stashing to improve data locality, de-allocating and cache maintenance transactions, as well as DVM message support for Armv7, Armv8 and Armv8.1 Cortex-A processors. Further, VIP is natively integrated with the Synopsys Verdi Protocol Analyzer debug system.

TI Tiny Op Amps
Texas Instruments (TI) has introduced a series of minuscule operational amplifier (op amp) and low-power comparators at 0.64 mm2. As part of the X2SON package, the TLV9061 op amp and TLV7011 family of comparators allow users to reduce their system size and cost while maintaining performance in a variety of Internet of Things (IoT), personal electronics and industrial applications.
With a gain bandwidth of 10MHz, slew rate of 6.5V/µs and spectral density of 10nV/√Hz, the TLV9061 op amp is designed for use in wide-bandwidth systems. The TLV7011 series of nanopower comparators also feature a faster response time with propagation delays down to 260ns, while consuming 50 percent less power.
Detailed schematics are available on TI’s website.
