Page 107 Highspeed COM Express Connector from ept
Chester, VA — The Colibri® COM Express connector from ept is now available with a new pinout, enabling data transfer rates of up to 10 Gb/s. The new Type 7 pinout does not include any audio or video inter- faces and cannot be used in place of Type 6. Instead, it expands the range of COM Express applications in servers. The audio and video interfaces
of the previous type have been replaced with four 10 Gb Ethernet KR lanes and 32 PCIe lanes to increase the rate of data transfer. These new features make the connec- tor suitable for video-on-demand applications, as well as in the med- ical or security technology fields. These areas of application require reliable PCB connectors, which are essential for securely connecting the baseboard with the COM module. Colibri connectors have an opti-
TI Develops Compact Step-Down Power Modules
Dallas, TX — Texas Instruments has introduced a pair of 12V, 10A, 4 MHz step-down power modules designed to provide a power management solu- tion that is, reportedly, 20 percent smaller than any other 10A power module-based solution currently available. The SWIFT™ TPSM84A21 and
TPSM84A22 DC-DC modules have integrated power MOSFETs, shield-
mized contact design and deliver sig- nal integrity, even at rates of 10 Gb/s and higher. They are suitable for PCIe Gen3 applications with 8 or 10 Gb/s Ethernet. S-parameters are available upon request for use in simulating proprietary designs. The versatile connector series has a pitch of 0.5 mm (0.02 in.) and is designed to be robust. Both the 220- and 440- pin versions for board-to-board dis- tances of 5 and 8 mm (0.2 and 0.3 in.)
are available. Contact: ept, Inc., 805 Liberty

ed inductors, input and output capac- itors, and passives in a small, low- profile package. The power modules provide as little as 1 percent over- shoot in transient conditions, with- out special magnetics or additional capacitors. By using the step-down power
modules together with the company’s WEBENCH® power designer, engi- neers can bring space-constrained telecom, networking, and test and measurement power supply designs to market quickly. The highly-integrated power
modules require only one external resistor for a complete 12V step- down power solution. For an applica- tion such as powering tightly-regu- lated field-programmable gate array (FPGA) rails, a typical 10A module can require up to 16 external capaci- tors. In comparison, the TPSM84A21 offers low output ripple due to its high switching frequency and inte-
grated 185 µF output capacitance. Contact: Texas Instruments,
