10544A buffers 5370A: 1K + 10pF in series connected from 10544A output to input of an ECL line receiver cascade.
5345A: 1K + 910pF in series connected from 10544A output to input of CC CB long tailed pair isolation amplifier. 1K from CC base to ground. Since the 10544A phase noise floor is relatively high (~ -145dBc for the later variants earlier versions had a significantly higher noise floor spec) using 1K in series adds little additional noise.
