Mini Modular Instruments > Logic Level Translators > PRL-425

Applications:

• Differential LVDS, RS422, LVPECL, NECL, PECL or TTL to NECL, RS422 or TTL Logic Level Translation
• Differential line driver/receiver
• Conversion of Differential Signals to Ground-Referenced Signals
• Essential Lab Tools for interfacing with High Speed Data Communications Equipment

Features:

• 1.5 GHz maximum Clock Rate for the PRL-425N and 300MHz for the PRL-425T
• Floating 100 Ω Universal Differential Inputs Accept LVDS, LVPECL, NECL, PECL, RS422 or TTL Inputs
• Complementary 50 Ω ECL Outputs for PRL-425N
• Complementary 50 Ω TTL Outputs for PRL-425T
• Ready-to-Use 1.3 x 2.9 x 3.9-in. Modules include a ±8.5V/1.4A AC/DC Adapter

Description:

The PRL-425N and PRL-425T are dual channel, universal input differential receivers with SMA I/O connectors. The floating 100 Ω inputs are designed for interfacing with differential signals within the common mode range of -2.4V to +4V. Therefore, they are compatible with LVDS, RS422, LVPECL, LVTTL/CMOS, NECL, PECL or TTL differential input signals. The PRL-425N has complementary NECL outputs for driving 50 Ω loads terminated to -2 V, floating 100 Ω loads or AC-coupled 50 Ω loads. The PRL-425T has complementary TTL outputs for driving 50 Ω or open circuit loads. They are also long line drivers, designed specifically for use with high speed data communications applications. Functional block diagrams of these devices are shown in Fig. 1 and Fig. 2. Model numbers with suffix TR, such as PRL-425NTR or -425TTR, have Triax input connectors instead of SMA input connectors.

The PRL-425N and PRL-425T are each housed in a 1.3 x 2.9 x 3.9-in. extruded aluminum enclosure, and each is provided with a ±8.5V AC/DC Adapter. Optional mounting brackets are available.
