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.
