PCIe packet switches are automotive-qualified for telematics and ADAS

Wed, Nov 06, 2019

The PI7C9X2G304EVQ and PI7C9X2G404EVQ PCIe 2.0 packet switches packet switches are automotive-compliant for use in telematics/ADAS, navigation systems, in-vehicle wireless routers, and emerging applications such as V2V and V2X communications. They offer three-ports/four-lanes and four-ports/four-lanes, respectively.

The switches are designed to increase the fan-out of PCIe ports on SoCs, ASSPs, microprocessors and FPGAs to support these advanced features in the automotive industry. Both the PI7C9X2G304EVQ and PI7C9X2G404EVQ are qualified to AEC-Q100 Grade 2, and have an operating temperature range of -40 to +105 degrees C. They are manufactured in IATF 16949-certified facilities.

Interoperability at the system level is guaranteed, confirms Diodes, through compliance with the PCI-SIG PCIe Rev 2.1 standard.

Advanced features include an integrated clock buffer and support for peer-to-peer traffic, delivering greater system performance. The low-power operation is complemented by link power management, including active-state power management L0 and L1, device-state power management D0, D3Hot and D3Cold. Power dissipation in L0 is 300mW (typical), dropping to 35mW in PCI-PM L1.1 D3Hot PM sub-state mode.

Latency for a packet running through the switch without blocking is 150nanoseconds, and latency tolerance reporting improves platform power management. While the default mode is cut-through, store and forward modes are also supported. Peer-to-peer traffic is enabled through access control service support.

Diodes manufactures and supplies application specific standard products within the broad discrete, logic, analogue and mixed-signal semiconductor markets. Diodes serves the consumer electronics, computing, communications, industrial, and automotive markets, supplying diodes, rectifiers, transistors, MOSFETs, protection devices, function-specific arrays, single gate logic, amplifiers and comparators, Hall-effect and temperature sensors, power management devices, including LED drivers, AC/DC converters and controllers, DC/DC switching and linear voltage regulators, and voltage references along with special function devices, such as USB power switches, load switches, voltage supervisors, and motor controllers. Diodes also has timing, connectivity, switching, and signal integrity solutions for high-speed signals.

Audio ADC quadruples far-field voice capture distance

Wed, Nov 06, 2019

Engineers can now achieve a 120dB dynamic range for clear, high-fidelity audio in smart home applications, says Texas Instruments (TI) as it introduces the TLV320ADC5140audio ADC. It can capture clear audio up to four times farther away than competing devices, claims TI. The TLV320ADC5140 is the industry’s smallest quad-channel audio ADC with this level of performance, says the company. It is part of a family of three TI Burr-Brown audio ADCs that enable low-distortion audio recordings in loud environments and far-field, high-fidelity recordings in any environment.

In smart home systems, a limited number of microphones and restricted signal processing capability make it difficult to capture and understand voice commands in loud environments. To meet this challenge, the TLV320ADC5140 enables engineers to improve audio capture from across rooms and boost recognition of soft-spoken commands in applications such as high-end smart speakers, sound bars, wireless speakers, high definition TVs, IP network cameras, tele-conferencing systems and smart appliances.

The TLV320ADC5140 provides clear audio capture in any environment in beamforming systems, says TI. It has a built-in 120dB dynamic range enhancer (DRE). At a system level, the DRE scheme boosts low-volume audio signals while maintaining low-distortion recordings, even at close proximity to the speaker output. The DRE also improves far-field, high-fidelity recordings in all environments.

The TLV320ADC5140 is believed to be the first ADC that fully supports the latest high signal-to-noise-ratio microphones with greater than 106dB dynamic range.

Up to four analogue or eight digital microphones can be converted and programmable features such as gain and phase calibration can equalise microphone-array mismatches. Other features include a programmable gain amplifier, high-pass filters, channel mixing, and linear phase or ultra-low-latency decimation filters.

The TLV320ADC5140 enables engineers to offload digital signal processing tasks, to shrink the size of designs while maintaining system reliability and minimising power consumption to only 9.5mW per channel at 48kHz.

The TLV320ADC5140 is available in a 4.0 x 4.0mm, 24-pin wafer quad flatpack no-lead (WQFN) packaging. The TLV320ADC5140 quad-channel 768-kHz TI Burr-Brown audio ADC evaluation module, the ADC5140EVM-PDK, is also available.

Automotive-certified level shifters assist ADAS development

Tue, Nov 05, 2019

Two high-speed, automotive-compliant voltage translators for use in environments with ambient temperatures up to 125 degrees C are available from Diodes. The PI4ULS5V108Q and PI4ULS5V202Q are designed for use in advanced driver-assistance systems (ADAS), infotainment, and telematics equipment.

Both shifters are compatible with either push-pull or open-drain connections. They have bi-directional flexibility with automatic direction sensing simplifies level shifting between bus interfaces, such as SMBus, PMBus, or I2C devices, by eliminating any requirement for a direction-control signal.

The eight-channel PI4ULS5V108Q performs up-translation at up to 100MHz and down-translation at over 100MHz. This performance makes it suitable for use in high data-rate interfaces, says the Diodes. Designers can ensure fast exchanges across SPI or other interfaces, with no limitation due to level shifting. This enables data transfers between system-on-chip (SoC) and peripheral components to be executed with optimum efficiency.

The PI4ULS5V202Q is a two-channel translator with internal 10kOhm pull-up resistors, allowing direct connection to interfaces with open-drain topology, such as I2C ports. The large maximum voltage-translation range of 1.2 to 5.5V enables the device to work with a variety of I2C chips and circuit designs. The PI4ULS5V202Q’s high-speed, one-shot detectors at the IC inputs result in fast rise and fall times. The PI4ULS5V202Q is able to support data rates of up to 20Mbits per second.

Both devices are AEC-Q100 grade 1 qualified, for automotive use and PPAP (production part approval process) -capable. They are in production at IATF 16949 certified sites.

The PI4ULS5V108Q is available now in the TSSOP-20 package and the PI4ULS5V202Q is offered in the MSOP-8 package.

Diodes manufactures and supplies application specific standard products within the broad discrete, logic, analogue, and mixed-signal semiconductor markets. Diodes serves the consumer electronics, computing, communications, industrial, and automotive markets. Products include diodes, rectifiers, transistors, MOSFETs, protection devices, function-specific arrays, single gate logic, amplifiers and comparators, Hall-effect and temperature sensors, power management devices, including LED drivers, AC/DC converters and controllers, DC/DC switching and linear voltage regulators, and voltage references along with special function devices, such as USB power switches, load switches, voltage supervisors, and motor controllers.
