Gigabit transformer modules from Pulse

Pulse, a Technitrol Company, has introduced dual- and quad-port extended-temperature gigabit discrete isolation transformer modules. With an operating temperature range of -40°C to 85°C, these modules are well-suited for industrial and ruggedized Ethernet and military computer, telecommunications and networking applications.

Smaller dimensions
The HX5400NL and HX5401NL quad-port modules and HX5200NL and HX5201NL dual-port modules are part of Pulse's Quattro (quad-port) and Dos (dual-port) series of high-density gigabit transformer modules. At 29-by-17.5-by-11mm (LxWxH) for the quad-port and 14.7-by-17.5-by-11mm for the dual-port, these modules are 50 percent smaller than currently available modules.

They are solder-bumped and tested for easy surface-mount attachment to the PCB. Small size and BGA design provide flexibility for designers to either fit more components on a PCB or to reduce PCB size using the same number of components. The quad-port module fits perfectly behind a 2x2 RJ45 connector, which makes board layout easier and more compact.

These modules are guaranteed to meet coplanarity of 0.005 inches. The solder-bump grid array interconnection enables high I/O density, fits in a small footprint, and can be applied with SMT assembly, further reducing costs. Inner layers of the PCB can be used for routing because there is not a high density of through-hole pins. In addition, these modules enable very reliable and high-yield interconnects.

The extended-temperature Quattro and Dos modules provide electrical circuit isolation to safeguard against electrical shock and reduce noise and EMI to maintain signal integrity. These RoHS- and IEEE 802.3-compliant parts have also been tested and validated by top-tier gigabit integrated circuit vendors.

Industrial Ethernet market
"The industrial Ethernet market is the fastest-growing market in the US and Europe. Worldwide, it looks poised to grow at a compound annual rate of 51.4 percent over the next three years," said William Malherbe, worldwide LAN marketing manager, Pulse. "With the introduction of these new extended-temperature gigabit modules, Pulse gives designers greater options for designing small packages for today's high-speed technologies."

The Quattro and Dos series discrete isolation transformer modules can be used with Pulse's unfiltered connectors, part numbers E5908-57A132-L and E5908-25A1J5-L, respectively. The modules are available in trays and are priced at $2.19 per port for 10,000 units. Price varies depending on order configuration and destination. Contact Pulse for high-volume pricing.
