1. All typical values are at 5.0 V and 25°C unless otherwise noted.
2. VOH and VOL can be set by the external resistor values on the PECL outputs.
3. IDD includes the current through the external resistors, which can be modified.
4. The phase relationship between input and output can change at power up. For a fixed phase
relationship, see one of the ICS zero delay buffers.
5. Except S1=0, S0=0 setting (This setting specific to 16 MHz in, 155.52 MHz out).
