The PLL1705 and PLL1706 use the same die and they are electrically identical except for mode control.

The PLL1705 are low cost, phase-locked loop (PLL) multiclock generators. The PLL1705 and PLL1706 can generate four system clocks from a 27-MHz reference input frequency. The clock outputs of the PLL1705 can be controlled by sampling frequency-control pins and those of the PLL1706 can be controlled through serial-mode control pins. The device gives customers both cost and space savings by eliminating external components and enables customers to achieve the very low-jitter performance needed for high performance audio DACs and/or ADCs. The PLL1705 and PLL1706 are ideal for MPEG-2 applications which use a 27-MHz master clock such as DVD players, DVD add-on cards for multimedia PCs, digital HDTV systems, and set-top boxes.
