The NBC12429FN is a 3.3/5.0V programmable PLL clock synthesiser that provides a 25 to 400MHz system clock ideal for the primary timing signals in networking, telecomms and test hardware.
Meritorious performance from N-channel MOSFETs
Continuing the expansion of its portfolio of low-voltage power MOSFETs for switching and power management applications, ON Semiconductor has released a range of new N-channel devices.
In an effort to provide designers additional options for meeting increasing stringent ESD and EMI standards, ON Semiconductor has also introduced the NUP2105L CAN bus protector and the NUP1105L LIN bus protector.
These devices improve the reliability of transceiver modules by providing noise immunity levels above and beyond that inherent in the bus system configuration.
"Increasingly, vehicle manufacturers are looking to simplify their supply chains by sourcing the majority of their automotive IC content from a smaller number of focused and reliable vendors", said Sri Jandhyala, ON Semiconductor Director of Automotive Market Development.

The new NUP2105L CANbus protector is a 27V dual bidirectional transient voltage suppressor (TVS) designed to protect the transceiver in high-speed and fault tolerant CAN networks from EMI and ESD.
The NUP1105L LINbus protector is a 27V single bidirectional TVS designed to protect the transceiver in LIN or single wire CAN networks from EMI and ESD.
"ON Semiconductors latest LIN and CAN protection devices are the only devices on the market today that offer a fully integrated solution based on an avalanche TVS technology for dual-wire CAN dataline protection", said Mamoon Rashid, ON Semiconductor Director of Marketing for Small Signal Products.
"This integration reduces both component count and board space usage which helps designers reduce overall system cost while improving system reliability".
The NUP2105L and NUP1105L absorb the energy of transient voltage events to prevent damage to the CAN or LIN transceiver.
The bidirectional configuration of the diodes prevents inadvertent clamping of normal dataline signals due to common mode voltage offset in systems with long cable lengths.
The low capacitance of the NUP2105L makes it ideal for systems with data transmission speeds up to 1Mbit/s.
This device complies with the ISO11898-2 physical layer specification and exceeds established industry standards for ESD and EMI immunity.
Ultimately, it provides the system designer with a low-cost option for improving system reliability and meeting stringent EMI requirements, particularly in mission-critical CAN network applications such as braking, engine and transmission control.
The NUP1105L TVS can be used to protect single dataline CAN and LIN communications systems.
This device increases the EMI and ESD immunity levels beyond the SAE J2411 and ISO7637-3 specifications, which increases the reliability of network in harsh automotive and industrial environments.
Distortion-free transmission of the data is provided by the small anode-to-anode capacitance of only 30pF.
The NUP1105L is a low-cost solution when compared to using multiple discrete diodes and TVSs for this application.
The NUP2105L is offered in a SOT-23 package and price at $0.09 per unit in 10,000-unit quantities.
The NUP1105L is also offered in a SOT-23 package and priced at $0.05 per unit in 10,000-unit quantities.
