1. Maximum test duration one second.
2. All DC parameters are tested or guaranteed by characterization.
The S4503 TTL outputs feature source series termination of approximately 40 Ohms to assist in matching 50–75
ohm P.C. board environments.
DC Characteristics
The S4503 has been designed specifically for clock distribution. In the development of this product, AMCC has
made several modifications to the historic “high drive, totem pole outputs” producing AMCC’s dynamically
adjusting source series terminated outputs. As a result of this, the S4503 will dynamically source and sink a
symmetrical 24 mA of current. In a DC state, it exhibits the following specifications:
