Low jitter for drop-in PLL synthesiser replacement
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.
Designed for portable communication devices requiring quality audio, these devices produce zero pop-and-click noise.
The NCP2892 is optimised to eliminate pop-and-click noise with differential audio input while the NCP2990 demonstrates the same zero pop noise feature with single-ended audio input.
These new audio amplifiers are ideal for cellphones and PDAs.
"ON Semiconductor continues to expand its audio amplifier portfolio to meet customer demand for high performance solutions that incorporate valuable end-product benefits - such as battery life conservation, fast turn-on times and elimination of unwanted noise", said Hyung-Sup Kim, ON Semiconductor's Director for the Consumer Products Division.
"The portable electronics market is highly competitive, with fast turn-around design times and frequent upgrades to the final handheld products".
"By working closely with our customers, ON Semiconductor is able to deliver targeted solutions".
For maximum design flexibility, the NCP2892 and NCP2990 feature an externally controlled turn-on time.
When using a 1uF bypass capacitor, the NCP2892 offers 100ms wake up time.
Both devices offer minimum turn-on time down to 15 to 30ms.
The NCP2892 and NCP2990 devices can be connected directly to the battery, eliminating the use of an LDO or DC/DC convertor and offering a cost effective solution.
Both the NCP2892 and NCP2990 are offered in a lead free (Pb-free) 9-pin Flip-Chip package and budgetary priced between US $0.44 and $0.45 per unit in 1000 unit quantities.
