Notebook Computing
Introduction
Your partner for notebook computing
Designing notebooks isn’t getting any easier. The footprint continues to
shrink, and consumers continue to demand more features, faster speeds,
and lower power consumption. There are always new protocols on the horizon,
and even standard feature sets require smart connectivity and smart energy
management.
NXP understands all this, and provides world-class solutions specifically
created to help designers deliver exceptional notebook systems. We build
on our decades-long leadership in high-performance mixed-signal solutions,
providing continuous innovation for each functional block. We specialize in
miniature packaging, and always make power efficiency a priority.
In this guide, you’ll find details on our complete range of notebook offerings,
including graphic interfaces, power management, audio systems, ESD
protection, system control, memory interfaces, and more.

High-speed graphics connectivity
1.1 High-bandwidth switches for
DisplayPort and PCIe
These devices maintain signal integrity by routing signals between single
and multiple sources. They lower system power, and they reduce pin-
count in the core chipset. They also help manage battery life, by letting
the system switch between discrete graphics during high-performance
operation powered by mains and integrated graphics when using the
battery. They deliver excellent performance and are available in cost-
effective, industry-standard packages.
Hex DisplayPort v1.1a and PCIe Gen 1/Gen 2 Muxes CBTL06121/22
Many chipsets use reconfigurable I/O to reduce the pin-count and
support a variety of interfaces. The CBTL06121/22 lets the chipset use
PCIe and DisplayPort interfaces using the same I/O. It has dedicated
channels for Aux and Hot Plug Detect (HPD), and is extremely useful
in notebook docking stations, where it can enable two DisplayPort
connections to the chipset. The device can also be used to switch
between discrete and integrated graphics, to save battery power.
