Device ID and SMBus Device Address
The device ID (SMB_A(1:0)) is part of the SMBus device address. The least significant bit of the address designates a write
or read operation. Table 3 shows the addresses for four ICS9214 devices on the same SMBus.
PLL Multiplier
Table 2 shows the frequency multipliers in the PLL, selectable by programming the MULT0, MULT1 and MULT2 bits in the
SMBus Multiplier Control register. Power up default is 4.

NOTES
1 Output frequencies are based on nominal input frequencies of 100 MHz and 133 MHz. The PLL
multipliers are also applicable to spread spectrum modulated input clocks.
2 Default muliplier value at power up
3 Outputs at these settings do not conform to the AC Output Characteristics, or are not supported.
4 Shaded areas are under development and are not yet supported
