If you are using a BGA package you probably have a buried power and ground plane so you can tie power and ground pins down to the appropriate plane with a local via per pin then you can somewhat afford to skimp a little (The planes have low inductance

performance devices may require a larger decoupling capacitor, or pairs or capacitors, such as 4.7 F and 100 nF capacitors in parallel. The decoupling capacitor works as a local energy storage, supplying large transient currents as necessary. Decoupling capacitors should have a good frequency response, such as monolithic-ceramic capacitors. Capacitor Choice & Placement Proper placement and location are very important for high-frequency capacitors (0.001 to 0.1 ВµF low inductance ceramic chip). Designers should minimize trace lengths when possible to reduce the inductance in the path

Using Decoupling Capacitors www.cypress.com Document No. 001-19299 Rev. *D 2 The impedance curve of Real capacitors resembles the traces marked 22-nF and 100-pF of Figure 3. A genetic algorithm (GA)-based method is proposed for simultaneous optimization of decoupling capacitors assigned to multiple pins of a ball-grid array (BGA) package on a printed circuit board.

The big caps do not have to be directly under BGA, unless they are part of smaller power rail. Think about the placement and start from the middle of the BGA. Also, you really may want to place all the through hole VIAs when you will be doing decoupling placement, so you are sure you can fanout all the signals. The purpose of decoupling is to provide clean, noise-free power supplies for SoC-internal power rails. Internal regulators are stabilized for a given capacitance and interaction between regulator modes relies on decoupling capacitors. Power supply decoupling capacitors must be selected with care to ensure sufficient effective capacitance

Decoupling the Power Distribution Network of the microcontroller IC is critical to the PCB design process, because careful selection of the decoupling capacitors and placement has a big influence on the high speed performance of the board, and can reduce the emissions. The on-board decoupling capacitors have an effective range of 1MHz – 200MHz. and closer component placements available. The latter is possible due to the reduced physical dimensions of SMDs. This is critical to two-layer board design, where maximum effectiveness from noise-control components is needed. Generally, leaded capacitors all go self-resonant (become more inductive than capacitive) at about 80 MHz. Because

For example the guide states that one 100 uF, one 4.7 uF and two 0.47uF capacitors should be connected to the power pins of Bank 1. According to this guide 100 uF capacitor could be placed almost anywhere near the IC, 4.7 uF should be placed within 2 inches of the outer edge and 0.47 uF should be preferably placed on PCB backside. High-Speed Layout Guidelines 1.3.1 Signal Speed and Propagation Delay Time A signal cannot pass through a trace with infinite speed. The maximum speed is the speed of light with 3 Г— 108 m/s. For a certain trace length, the signal needs a certain time to pass it, and this is called the propagation delay time. The standard medium for the speed

For example, if current demand in the device increases in a matter of nanoseconds, the voltage at the device will sag by some amount until the voltage regulator can adjust to the new, higher level of current it must provide. The second major component of the PDS is the bypass or decoupling capacitors. In this

For an example, a large, ball grid array (BGA) device will have many power and ground pins. Often, decoupling capacitors are placed on the bottom side of the PCB across the BGA escape vias in order to minimize the connection inductance seen by the capacitor. If the power/ground plane pair in this example is close to the top of the PCB, then the With 100,000 of these tiny (2u by 5u, for example) capacitors all over the silicon, there is lots of capacitance because the Cs add up. The Rs reduce, because in parallel. And the inductances reduce, because in parallel.

These sections also present a these and other capacitors for high frequency applications, a useful value can be ensured by selecting a capacitor which has a self-resonant frequency above the highest frequency of interest. In general, film type capacitors are not useful in power supply decoupling applications because they are generally wound, which increases their inductance

Decoupling capacitor explained. A decoupling capacitor is a capacitor used to decouple one part of an electrical network (circuit) from another. Noise caused by other circuit elements is shunted through the capacitor, reducing the effect it has on the rest of the circuit.
