The latest generation family of one to four phase lock loop [pll] clock generator devices from texas instruments is the most advanced instruments. These clock generator devices are highly programmable and can generate up to nine output clock sources from only single input frequency. The user can set the output in the clock generator devices for any clock frequency with up to 230 mhz. These unique features of the clock generator devices offer advantages like low power consumption, low lead time and flexibility for upgrading clock without redesigning. The clock generator devices lower the cost of the applications. Texas family of clock generator devices are useful for applications like ip set-top boxes or phones, digital televisions, streaming media and printers, navigation systems and portable devices. The company supplies these clock generator devices in ranges of cdce9xx & cdcel9xx family with one to four plls and a reduced jitter at 60 picoseconds. The texas cdcel9xx family of clock generator device is available with 2.5-v or 3.3-v outputs, whereas the cdcel9xx devices offer 1.8-v outputs. This technical feature of the both devices enables low-power facility for portable devices. The company provides clock generator devices with pll to support spread-spectrum clocking [ssc] for reducing electromagnetic interference [emi] to comply with emc regulations.
