Applied Micro Circuits Corporation (AMCC) uses proprietary complementary (source and sink)24 mA peak output drivers. In addition to their drive capability, these circuits provide "source (series) termination"at the TTL outputs that minimize over/undershoot without requiring on-board termination networks. They are designed for a maximum output slew rate of =1.5V/ns to minimize simultaneous out-
put-switching noise and distortion.
Feature
·20 clock outputs:
-Ten or twenty outputs(SC3308) at primary frequency, up to 80 MHz
