Touted by Texas Instruments Inc. (TI) to offer a best-in-class performance, the company's latest clocking IC features three on-chip phase locked loop (PLL) filter components.

According to TI, the new clock multiplier's architecture eliminates the need for external components to support PLL structures, which reduces overall system cost and conserves board space. Featuring low period jitter and the ability to generate multiple clock frequencies, the technology behind the device is suitable for consumer electronics such as game systems, DVD player/recorders, digital TVs and STBs.

From a 54MHz system clock, the CDC5806 generates a video, audio, CPU, USB and portable memory clock out of a single device. The three PLLs generate the various output frequencies from the system clock, and the on-chip loop filters and internal feedback eliminate the need for external components.

Developed in TI's RF SiGe process, the highly-integrated product operates from single 3.3V supply and between the -40C to 85C temperature range. Its clock input accepts single-ended LVCMOS.

Housed in a 20-pin TSSOP package, the CDC5806 has a suggested resale price of $2.15 each in quantities of 1,000 units.
