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.
These devices were designed with the high power demands required in high-end audio applications, including professional audio amplifiers, theatre and stadium sound systems, and public address systems (PAs).
The MJL4281A (NPN) and MJL4302A (PNP) are 15A, 230W PowerBase power transistors that feature 350V collector-emitter sustained voltage.
Competitive devices available for these applications are only available up to 230V.
The devices deliver high bandwidth and high-gain linearity.
The devices feature an excellent safe operating area (SOA) allowing 1.2A collector current and 100V at 1s enabling high bandwidth and clean, low-distortion output.
With uniform linearity from 0.1 to 5A the devices deliver accurate reproduction of input signal.
High gain (80 to 250) results in greater amplification of output signal.
The MJL4281A and MJL4302A amplifiers are offered in the TO-264 package and priced at $1.85 per unit in 10,000-unit quantities.
Drivers to complement these high voltage output transistors also have been released.
The MJE15034 and MJE15035 are available in TO-220 packages priced at $0.36 per unit in 10,000-unit quantities.
