*SPECIFICATIONS
Unless otherwise specified, dynamic measurements are made with all outputs terminated into 50Ω/V
Notes:
(1). The output rise and fall times are measured with both the Q and
NECL/PECL Terminators, connected to a 50Ω input sampling oscilloscope. V
and fall times will increase by approximately 15%, due to slight degradation of the pulse corners.
(2). f MAX for the PRL-420ND is measured by connecting its inputs to the PRL-450ND, NECL to TTL Logic Level Translator, and its outputs to the ÷2 differential
inputs of the PRL-255N NECL frequency divider. The outputs of the PRL-255N are then measured using the PRL-550NQ4X, four channel NECL Terminators,
connected to a 50 Ω input sampling 'scope. Similarly, f MAX for the PRL-420PD is measured using the PRL-450PD as the input driver, and its outputs are connected to
the differential inputs of the PRL-255P PECL frequency divider. The outputs of the PRL-255P are then measured using the PRL-550PQ4X, four channel PECL
Terminators, connected to a 50 Ω input sampling 'scope.
