This project grew out of the need to generate a linear crystal controlled ramp signal for the HP 8620C RF Sweep Oscillator. It was inspired by a previously released ramp generator design. There are two problems with this design: it uses a non-standard 16.384MHz crystal oscillator; its ramp has zero fall/return/blank times.

Allegro MicroSystems, Inc. offers two new full bridge door drivers for automotive and industrial applications. The A89505 and A89506 are excellent in automotive applications where both drives contain built-in current sensing capabilities, eliminating the need for external current sensing resistances and reducing the requirement for external components to a minimum of seven. Both can provide an absolute maximum supply voltage of 50V. Both devices have current limit detection flags that trigger when programmable current limits are reached
Diodes Incorporated introduced PCIe 3.0 packet switching ICs. The basic architecture of the device consists of two magnetic blocks, each with 8 ports and 16 channels, which enables it to support SERDES configuration options of 32 channels, ranging from two ports to 16 ports. Multiple DMA channels are embedded into the device to allow more efficient data communication between host/host and connected endpoints, advanced power management features allow significant power savings
Global chip prices have risen 10-20 per cent in the past year and are likely to continue to rise by 5-7 per cent this year.
Infineon Technologies AG extends the LITIX Power line with the dual-channel, standalone DC-DC controller TLD6098-2ES. As a multi-topology controller, it supports boost, buck, SEPIC, and flyback topologies with wide input voltage ranges from 4.5V to 60V and even 24V battery system applications.
U-blox has released MAYA-W2 three radio modules. The module supports Wi-Fi 6, BLE 5.2, and IEEE 802.15.4 (Thread and Zigbee) in compact form. The module FutureProof applications with a set of advanced connectivity features. The dual-mode Bluetooth module supports Bluetooth Classic and Bluetooth LE, including Bluetooth LE Audio, This professional level module can work in the -40C-85C range.
Diodes Incorporated has introduced automotive compatible diode AP61300Q and Diodes AP61302Q synchronous buck converters. These step-down converters include a 70mOhm high side power MOSFET and a 50mOhm low side power MOSFET. Together, they provide efficient step-down dc-dc converters, and the device can be configured for PFM or PWM operating mode (using enable pins).
Mouser provides a number of solutions from Phoenix Contact. The Axioline P I/O system is CE, UL, EX, and Class A certified and hot-swappable for time saving and ease of use. The company's monitors and keyboards offer high-contrast capacitive touch displays and thin-film keyboards, providing user-friendly interfaces for operators and a broad portfolio of solutions for energy storage systems, including connectors, terminal blocks, contacts, and more.
Infineon Technologies Bipolar GmbH & Co. KG extends the high power Prime Switch range with a new laminated IGBT (PPI) with FWD inside ceramic disc housing. At 3000A without FWD, the blocking voltage is 4.5kV. With FWD, the blocking voltage is 2000A. PPI enclosures are sealed and specially developed to withstand system induced failures.
Onmi Pro Electronics has added Tecate Group's new 3V TPLH series of small cell supercapacitors to its extensive PORTFOLIO of TPL and TPLH 2.7V small cell supercapacitors. The new series provides a way to achieve higher voltages and higher energy densities within the same industry-standard battery footprint, thereby saving space and potentially reducing the number of cells required. This series of ultracapacitor batteries range from 4F to 100F. They are UL certified and meet RoHS and REACH standards.
Fairview Microwave Inc. now offers a new line of 5G outdoors-rated omnidirectional antennas for the 4G, 5G, LTE and CBRS bands. Its new 5G omnidirectional antenna offers range expansion and simple deployment to build wireless lans, cellular communications networks and private networks. These collinear omnidirectional antennas provide n-type connectors and are ideal for SISO or MIMO operations
IQD offers iqcm-200, a rigorous OCXO that includes 1PPS input and 1PPS output synchronization. The device is part of a series of disciplined OCXOs. This "best in class" retention stability of 1.5μs in 24 hours at 0-60C and typical retention stability of 25 μs in 10 days at 25±2C is achieved by an adaptive algorithm.
Flex Power Modules has released an enhanced version of the BMR350 non-isolated quarter brick DC-DC bus converter, the BMR350 X250/531. The product remains the same size 58.4mm x 36.8mm, height only 12mm, input range 40-60VDC (80V/ 100ms) the same. Like the original device, the product is excellent as an intermediate bus converter for powering processors and ASics with peak power requirements.
