Hi,
I am attempting to use the TI CDCE62005 to generate 50M, 100M and 150 MHz from a 25MHz crystal.
I am using the GUI to calculate the dividers. The device wont lock in the GUI (not sure the little light actually indicates 'LOCK') and in real hardware.
In a previous thread, a guy had the same problem, and a fella named Lane Boyd helped him. Lane stated that he 'calibrated' the chip, that option is always GREYed out for me.
After boot, I have an FPGA program the CDCE62005 via SPI,
Here are the values generated so far:
REGISTERS
0 EB800300
1 EB140301
2 EB0A0302
3 EB020303
4 EB840314
5 10000B25
6 340E02B6
7 950037F7
8 20009D98
PORTS
0 9D
1 FF
2 DF
3 F9
INPUTS
PRI 0
SEC 0
AUX 25
EXTERNAL COMPONENTS
C4 0f
R4 0f
C5 0f
Ideally I do not want to use any external components but if necessary I will.
