... FS0-FS3. Similarly, the auxiliary PLL can generate any one of four pre-programmed frequencies via the MS0 & MS1 lines. A unique feature of the ICS2595 is the ability to redefine frequency selections in both the VCLK and MCLK synthesiz- ers after power-up. This permits complete set-up of the frequency table upon system initialization ...

... The FS0-FS3 pins and the STROBE pin are used to select the desired operating frequency of the VCLK output from the 16 pre-programmed/user-programmed selections in the ICS2595. These pins are also used to load new frequency data into the registers. The standard interface for the ICS2595 matches the interface of the industry standard ICS2494 ...

... ICS2595 LATCHED FS inputs, not the FS inputs themselves, that are interpreted by the internal logic. Interface logic resides between the FS input pins and the programming/frequency select logic. The appropriate "data write" procedure must be observed. See the section "Digital Interface" in this supplement for more information. ...

... If a 14.31818 MHz reference is used, the output frequency range would be from 10.697 MHz to 170.486 MHz (but the upper end is first limited to 145 MHz by the ICS2595 output driver). Programming Example Suppose that we want differential CLK output to be 45.723 MHz ...

... Power Supply The ICS2595 has three GND pins to reduce the effects of package inductance. All pins are connected to the same potential on the die (the ground bus). All of these pins should connect to the ground plane of the video board as close to the package as is possible ...
