Buffer Characteristics
Current Mode CPU Clock Buffer Characteristics
The current mode output buffer detail and current reference circuit details are contained in the previous table of this
data sheet. The following parameters are used to specify output buffer characteristics:
1.
Output impedance of the current mode buffer circuit - Ro (see figure below).
2.
Minimum and maximum required voltage operation range of the circuit – Vop (see figure below).
3.
Series resistance in the buffer circuit – Ros (see figure below).
4.
Current accuracy at given configuration into nominal test load for given configuration.
