SAN DIEGO--(BUSINESS WIRE)--June 28, 2001--Pulse announced a new single-port PulseJack(TM) RJ-45 connector with integrated magnetics and telephone network voltages (TNV) circuit protection.
The new connector integrates isolation transformers and line-side protection creating a single-port T1/E1 solution. This PulseJack(TM) family of RJ-45 connectors successfully passed rigorous tests conducted by Contech Research, a leading independent connector evaluation firm.
The J1501F21 is a through-hole, tab-up RJ-45 jack designed to interface with PMC-Sierra transceivers PM4351 and 4354 for long-haul and short-haul applications and can be used with many other chipsets. PulseJack(TM) models matched to other leading T1/E1 IC manufacturers such as Intel, Dallas Semiconductor and Exar are also available.
In telecommunications applications such as modems for computers, notebooks, and servers, protection of circuitry is needed to prevent equipment damage caused by over-voltage and over-current surges due to line voltage surges, lightning strikes and/or AC power cross disturbances.
Fully matched and compatible with PMC-Sierra's transceivers when used with recommended chip side protectors, the PulseJack(TM) RJ-45 connector has been designed to meet the surge immunity and electrical safety standards, including Bellcore GR-1089, FCC Part 68 and UL 1949/1950.
With integrated magnetics, voltage surge protectors, and over-current protectors, the new PulseJack(TM) RJ-45 connectors deliver improved electrical performance and a built-in RJ-45 receptacle in one package.
The PulseJack(TM) is a space-efficient module, which minimizes the electrical trace length between the RJ-45 connector and Integrated Circuit Transceiver, again improving both electromagnetic interference (EMI) protection and electrical performance.
``This new design reflects our commitment to developing cost-effective, high-performance magnetic solutions for the OEM market,'' said Pulse Telecom product line manager, Mukesh Mehta. ``This new connector lowers manufacturing costs, saves board space and improves both electrical performance and EMI protection.''
The transfer-molded connector module utilizes Pulse's patented interlock base construction, which minimizes the stress of human handling during assembly and encapsulation, thus resulting in more uniform positioning of coils, leads and interconnecting wires which in turn provides a higher part quality and reliability.
