*SPECIFICATIONS
Notes: (1). The NECL 50 Ω output rise and fall times (20%-80%) are measured with both the Q and
terminated, both the rise and fall times will increase by approximately 15%, and output waveform degradation will occur. The TTL outputs rise and fall times (10%-
90%) are measured with ground referenced 50 Ω terminations, and it is not necessary to terminate an unused output.
(2). f
550NQ4X, four channel ECL Terminators, connected to a sampling 'scope. f
(3). Units with the Trompeter CBBJR79 Triax input connectors are tested using the PRL-433N, complementary NECL input to Differential NECL output translator,
and the Trompeter PCGOW10PCG-36 shielded twisted pair cables.
