Hardware overview of possible ReaderClocks

Only some specific frequencies are possible, here is a list of them:

PPC-Dreambox DM500/DM600/DM7000/DM7020

Possible CardClocks (PLL = 31.50Mhz):
1.96 Mhz
2.86 Mhz
3.15 Mhz
3.50 Mhz
3.93 MHz
4.50 Mhz
5.25 Mhz
6.30 Mhz
7.87 Mhz
10.50 Mhz
15.75 Mhz
31.50 Mhz

Mips-Dreambox DM500HD, DM800(se), DM900HD, DM7020HD, DM8000HD, DM7080HD

Possible CardClocks (PLL = 27Mhz):
1.68 Mhz

PCSC (Omnikey and others)

Oscam can not change the clock.
Clocked by Firmware (Normaly 4.00 Mhz or 4.80 MHz)
Omnikey can be changed with "HID Workbench" (​http://www.hidglobal.de/drivers/14993)
