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 14
).
2. Minimum and maximum required voltage operation range
of the circuit – Vop (see
Figure 14
).
3. Series resistance in the buffer circuit – Ros (see
Figure 14
).
4. Current accuracy at given configuration into nominal test
load for given configuration.
