DESCRIPTION
The PLL1707 is a low-cost phase-locked loop (PLL) multiclock generator. The PLL1707 can generate four system clocks from a 27-MHz reference input frequency. The clock outputs of the PLL1707 can be controlled by sampling frequency-control pins. The device gives customers both cost and space savings by eliminating external ponents and enables customers to achieve the very low-jitter performance needed for high performance audio DACs and/or ADCs. The PLL1707 is ideal for MPEG-2 applications that use a 27-MHz master clock such as DVD recorders, HDD recorders, DVD add-on cards for multimedia PCs, digital HDTV systems, and set-top boxes.
