PRL-420LPD Pulse Research Lab Dual Channel TTL to LVPECL Logic Level Translator

The Pulse Research Lab PRL-420ND/PD/LPD Dual Channel Translators are respectively, dual channel TTL/CMOS to NECL,TL/CMOS to PECL and TTL/CMOS to LVPECL Logic Level translators. Each unit has a switch-selectable 1.5V or 1V input threshold voltage. The PRL-420ND has a pair of complementary NECL outputs suitable for driving 50 Ω loads terminated to -2V. The complementary PECL outputs from the PRL-420PD are suitable for driving 50Ω loads terminated to +3V. The outputs of both units can also drive AC coupled or floating 50 Ω.

These The Pulse Research Lab PRL-420ND/PD/LPD Logic Level Translators are designed specifically for use in testing and interfacing of high speed digital communications circuits, where conversions from TTL/CMOS level signals to NECL and PECL level signals are often required. They are ideal building blocks that complement other PRL Logic Level Translators, such as the PRL-450ND, PRL-450PD, PRL-460NPD and PRL-460PND, etc. in systems integration applications where interconnections of mixed logic signals are often necessary.

They are ready-to-use functional modules housed in 1.3 x 2.9 x 3.9-in. extruded aluminum enclosures and are supplied with ±8.5V AC/DC Adaptors. These units have BNC input connectors and SMA output connectors.
