FS6131-01/FS6131-01g Programmable Line Lock Clock Generator IC
Data Sheet
10.3.1 Device Mode
The device mode block presets the demo program to program the FS6131 either as a frequency synthesizer (a stand alone clock generator) or
as a line-locked or genlock clock generator.
Frequency Synthesis: For use as a stand alone clock generator. Note that the reference source is the on-chip crystal oscillator, the expected
crystal frequency is 27MHz, and the voltage tune in the crystal oscillator (i.e. the VCXO) is disabled. The default output frequency (CLK freq.)
requested is 100MHz, with a maximum error of 10ppm, or about 100Hz. The output stage defaults to CMOS mode.
Line-Locked/Genlock: For use in a line-lock or genlock application. Note that the reference source is the REF pin, and that the expected
reference frequency is 8kHz. The default output frequency requested is a 100x multiple of the reference frequency.
10.3.2 Example: Frequency Synthesizer Mode
By default the demo program assumes the FS6131 is configured as a stand alone clock generator. Note that the reference source defaults to the
on-chip crystal oscillator, the expected crystal frequency is 27MHz, and the voltage tune in the Crystal Oscillator block (i.e. the VCXO) is
disabled. The default output frequency (CLK freq.) requested is 100MHz, with a maximum error of 10ppm, or about 100Hz. The Output Stage
defaults to CMOS mode. The Loop Filter block is set to internal, and the Check Loop Stability switch is on.
As an exercise, click on Calculate Solutions. The program takes into account all of the screen settings and calculates all possible combinations
of reference, feedback and post divider values that will generate the output frequency (100MHz) from the input frequency (27MHz) within the
desired tolerance (10ppm).
A box will momentarily appear: "Calculating Solutions: Press cancel to stop with the solutions calculated so far." A number in the box will increment
for every unique solution that is found. This example will create six unique solutions, which are then displayed in a window in the lower right portion
of the program screen.
The best PLL performance is obtained by running the VCO at as high a speed as possible. The last three solutions show a VCO speed of 200MHz.
Furthermore, good PLL performance is obtained with the smallest dividers possible, which means solution #4 should provide the best results.
Figure 20: Frequency Synthesizer Screen
Clicking on Solution #4 highlights the row, and clicking on Disp/Save Register Values provides a window with the final values of key settings. A
click on OK then displays a second window containing register information per the register map. If the solutions are to be saved to a file, two
formats are available: a text format for viewing, and a data format for loading into the FS6131.
Note: As an update to this data sheet, the FS6131 hardware is no longer available from AMIS.
