†

The 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.

Product

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments

semiconductor products and disclaimers thereto appears at the end of this data sheet.

†

The PLL1707 and PLL1708 use the same die and they are electrically identical except for mode control.
