why go for 20MHz
01/01/70 00:00
No 4 layer PCB & faster ADC available

not an analog eagle
01/01/70 00:00
Why not
01/01/70 00:00
not objecting, just wondering

Go for CPLD or not !
01/01/70 00:00
Not in that timescale
01/01/70 00:00
so about 10K gates are needed ?
01/01/70 00:00
part numbers
01/01/70 00:00
Wow pretty expensive !
01/01/70 00:00
I'll have to wait till tommorow
01/01/70 00:00
