Board makers set their sights on PMC Product News 1/27/1999 Post a comment The most popular and versatile medium today for adding off-the-shelf or custom functionality to a system board is the PMC standard, a.k.a. PCI Mezzanine Card or, more formally, IEEE 1386.1. Most commonly fielded in a 2.9 x 5.9-inch format, PMC is available in a broad array of boards. Dozens of companies add graphics, communications, networking and other functions to a CPU or DSP system board. Complexity ranges from boards with a few serial ports to full-fledged processing boards that pack a micr
Mill-Max has SIMM adapters Product News 1/27/1999 Post a comment Single-in-line memory modules can be mounted perpendicularly to the motherboard using an adapter from Mill-Max that can be hand- or reflow-soldered to the edge of a 0.062-inch-thick board.
Capacitors are very stable Product News 1/27/1999 Post a comment Series MPP single- and three-phase power-correction capacitors and assemblies from Seacor Inc. are designed with extremely low-loss polypropylene dielectrics, resulting in stable electrical characteristics and life expectancies up to 100,000 hours.
Oscillators have a low profile Product News 1/27/1999 Post a comment Cardinal Components Inc. now has surface-mount TCXOs and VC-TCXOs in 2.5-mm high, leadless packages. They can be specified with sine-wave or square-wave output, with or without a voltage-control option.
Surface-mount fuses are fast Product News 1/27/1999 Post a comment Bel Fuse Inc. has launched fast-acting surface-mount chip fuses in EIA 0603 format. The C2Q, designed for both infrared reflow and wave-soldering processes, is rated from 0.25 to 4 A at 32 Vac/63 Vdc.
Desktop drives target reliability as speed, capacity rise Product News 1/22/1999 Post a comment Drive makers are increasing rotational rates to address the power user and at the same time are focusing on ways to increase reliability and thus decrease the number of drives they have returned. Both Quantum Corp., based here, and Western Digital Corp. (Irvine, Calif.) are unveiling 7,200-rpm drives that use proprietary techniques to safeguard up to 18 Gbytes of data.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
