While all the bits of CE [6:1] are 0, the PLL1706 goes into the power-down mode, all dynamic operation including PLLs
and the oscillator halt, but serial mode control is enabled for resumption.
CONNECTION DIAGRAM
Figure 14 shows the typical connection circuit for the PLL1705. There are four grounds for digital and analog power
supplies. However, the use of one common ground connection is recommended to avoid latch-up or other
power-supply-related troubles. Power supplies should be bypassed as close as possible to the device.
MPEG-2 APPLICATIONS
Typical applications for the PLL1705/6 are MPEG-2 based systems such as DVD players, DVD add-on cards for
multimedia PCs, digital HDTV systems, and set-top boxes. The PLL1705/6 provides audio system clocks for a CD-DA DSP,
DVD DSP, Karaoke DSP, and DAC(s) from a 27-MHz video clock.
