Because they use SSTL and HSTL I/O signaling interfaces, some high-speed memories, like FCRAMs and RLDRAMs, can only deliver their optimal performance when connected point-to-point to the NPU. (Compared to other interfaces, SSTL signaling also uses more power.) In contrast, RSL signaling allows multiple memory chips to be connected on a bus (called multidrop), thereby paving a convenient way to increase a line card's total memory capacity, even in the field. Multidrop bus support also gives designers the flexibility to target one basic line-card design for a range of applications and market segments.

The key concept to note is the addition operation is timed by the availability of the data and the adder functional block.

There are several different modulation techniques that designers can employ when developing frequency-hop or direct-sequence systems. Information modulation can be accomplished using amplitude (AM) of frequency modulation (FM) techniques. AM is normally used because it tends to be detectable when examining the spectrum. FM is more useful because it is a constant-envelope signal, but information is still readily observed. In both AM and FM, no knowledge of the code is needed to receive the transmitted information.

The AICH signal consists of 15 consecutive access slots of 5120 chips in length (Figure 2) . Each access slot contains an acquisition indicator of 32 real-value symbols (a0, a2,…., a31) and a period of 1024 chips with transmission turned off.

In a centralized fabric chipset configuration, both the queue scheduler and the switching (crossbar) chips of the fabric chipset reside on fabric cards. In a distributed configuration, the queue scheduler component of the fabric chipset resides on the line card while the crossbar chip resides on the fabric card. While a centralized configuration offers a low cost solution, the distributed configuration allows a system to be shipped with fewer line cards and fabric cards and upgraded with more line and fabric cards as the demand grows.

To date, metro networks are predominantly implemented with ADMs in point-to-point and ring architectures, capable of grooming down to the STS/AU level. A significant portion of VT/TU level cross connection takes place in digital cross-connect systems (DCSs) centrally located in the metro core.

In the past, you may have handled these various functions using separate, individually packaged components interconnected on the printed-circuit board. With the development of the SoC, integration and compatibility issues that previously were managed in the board design now must be handled in the IC and package design. Two examples of these new challenges are designing the power distribution to control switching noise and protecting analog circuits from noise generated by the switching activity of a digital bus. The PC boards are smaller, simpler and cheaper, but these advantages come at the expense of a more difficult design and increased complexity in the package and the IC.

The secondary voltage is then a square wave, and its fundamental passes through the output resonator to create a sinusoidal output current. This sinusoidal output current is supported on the input winding by two half sinusoids flowing alternatively in the bottom half and top half of the input winding (and hence alternatively through the top transistor and the bottom transistor). Since the current flows in each device when the drain voltage is zero, and since no current flows when the drain voltage is +2 Vcc , no power is absorbed by the devices and the theoretical efficiency is 100 percent.
