DESCRIPTIONThe PLL1707† and PLL1708† 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.
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate
precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to
damage because very small parametric changes could cause the device not to meet its published specifications.
