The PLL1707 and PLL1708 use the same die and they are electrically identical except for mode control.
Description for the PLL1707
The PLL1707 are low cost, phase-locked
loop (PLL) multiclock generators. The PLL1707 and
PLL1708 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 and those of the PLL1708 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 PLL1707 and PLL1708 are ideal
for MPEG-2 applications which 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.
