PRL-550NQ4X/PRL-550PQ4X FOUR CHANNEL NECL/PECL

TERMINATORS

INTRODUCTION

NECL/PECL logic levels are offset from ground. Without proper level shifting, these logic signals can not be connected to ground

referenced 50Ω input instruments, such as sampling 'scopes, network analyzers, scanners and counters, etc. Otherwise, either the

NECL/PECL equipment outputs or the measurement instrument inputs may be made inoperative or damaged.

When driving a length of 50 Ω coaxial cable, an NECL/PECL output must be terminated into a 50 Ω load that is connected to a

terminating voltage V

NECL/PECL Terminators are level translators which convert NECL/PECL signals into signals that can be connected to ground

referenced 50Ω input instruments and, at the same time, provide standard 50Ω/V

DESCRIPTION

The PRL-550NQ4X and PRL-550PQ4X are, respectively, Four Channel NECL and PECL Terminators. The PRL-550NQ4X is

designed to interface with NECL circuits operating with a -5.2V or -4.5V supply. Each input has an equivalent 50 Ω resistor

terminated to a voltage V

Each input has an equivalent 50 Ω resistor terminated to a voltage V

direct connection to ground referenced 50 Ω input instruments as shown in Figs. 1 and 2, respectively. These near ground level

output signals* protect sensitive instruments and enhence measurement accuracy when these instruments are used.

Once an NECL or PECL signal is translated through a proper Terminator, it can be routed through 50Ω scanners and other high

frequency measuring instruments for processing. Each PRL-550NQ4X and PRL-550PQ4X Terminator is housed in an attractive

1.3 x 2.9 x 2.2-in. extruded aluminum enclosure and is supplied with a ±8.5V AC/DC Adapter.

When connected to an NECL/PECL device, the output low level will be slightly offset from ground depending on the low level output voltage of the connected device, which is typically Vcc-1.8 V. When its input is connected to an NECL or PECL device, the Terminator output Low level is typically +50 mV. ≤ ...
