Notes:
(1). The NECL 50 Ω output rise and fall times (20%-80%) are
measured with both the Q and Q
outputs terminated into 50 Ω/-2 V. If one output is not
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). fMAX I is measured by dividing the outputs by four, using the PRL-255N,
÷2 and
÷4 frequency divider module, and then measured using the PRL-550NQ4X,
four channel ECL Terminators, connected to a sampling 'scope.
(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. Specified fmax is
limited to 625 MHz due to test equipment limitations, not due to any
inherent limitation in the Triax connector
All PRL products with Triax connectors use Trompeter P/N
CBBJR79, Right Angle Circuit Board Bulkhead Jack, 3-lug (Page 11
of
Trompeter
Mil/Aero Catalog). Any Trompeter 70-series Triax Cable Plug with 3 lugs (e.g.
PL75-9, 3-lug) will mate with CBBJR79. Cable Plugs are on Page 9
of
Trompeter
Mil/Aero Catalog.
