DescriptionThe PRL-454LV is a 1:4 LVDS fanout buffer and line driver. The floating 100 Ω universal differential input will receive LVDS, LVPECL*, NCML, or RS422 inputs with at least 300 mVPP differential input swing. Therefore the PRL-454LV can also be used to translate many different differential signal types to LVDS. The four pairs of complementary outputs are designed for driving floating 100 Ω loads, normally the configuration used in LVDS input circuits. The differential output swing is typically 300 mV with a common mode voltage of 1.0. All output connectors are SMA. The simple power supply requirements, +8 to +12 VDC/150 mA, allow the PRL-454LV to be used in many low power, portable applications in the field as well as in the lab. The PRL-454LV-SMA is supplied with a ±8.5 V/1.8 A AC/DC adapter and housed in a 1.3 x 2.9 x 2.9-in. extruded aluminum enclosure. The PRL-454LV-SMA may also be ordered without the power supply as part number PRL-454LV-SMA-OEM. A maximum of four units can share the included PRL-760E AC/DC adapter using additional units of cable #88000102-4. If mounting is desired, a pair of the #35001420 mounting brackets can accommodate any two PRL modules of the same length. *LVPECL drivers must have internal pull-down resistors to drive the floating load of the PRL-454LV. For translating LVPECL signals that lack internal pull-downs, use PRL-426LP, 2 Ch. LVPECL to LVDS Translator, with VTT/1.3 V LVPECL input terminations. |
