Interface products for speed and integrity

As chipsets get faster, you can look to NXP's complete high-end interface portfolio to add value to your design. By surrounding the core with high-speed multiplexer/demultiplexer switches, level shifters covering various voltages and application-specific redrivers, you increase functionality as well as system performance. You can maintain signal integrity on the board, compensate for system level signal loss, and drive signals over longer distances or to another PCB.

Fast flexible connectivity bridges and UARTs

End-users typically want a new computer system to support the latest standards, but their set-up may include older items that don't yet support the new specifications. That means system designers need to look to bridge solutions to support legacy peripherals while continuing to offload analog processing from the core processors.

This is especially true for display standards, with end-users often upgrading their computer but keeping their exisitng monitor. Next-generation systems already offer native DisplayPort (DP) support to enable high-definition video and 3D TV, but increasingly don't support VGA or LVDS. NXP offers highly configurable, field-upgradable bridge ICs with on-chip flash memory capable of converting the DP protocol to these legacy standards.

A family of UART-based products create simple, low-power, low-voltage connections to widely used legacy interfaces such as I2C, GPIO, IrDA, SPI, and UART functions. Another family of Protocol Converters connect I2C/SPI slave or UART functions to I2C/SPI masters or GPIO Devices.

Improved signal conditioning with greater reliability

NXP offers a family of high bandwidth level shifters that support DP-DVI and DP-HDMI signal conversion. Additionally, when designers demand improved signal integrity with greater reliability while driving high speed signals over longer lines, NXP provides high bandwidth products with low return loss and high gain. Building on state of the art mixed-signal expertise, NXP is developing a line of standards-compliant redrivers that improve signal conditioning in more demanding environments.

High speed switches to 10G and beyond

NXP offers a wide range of innovative multiplexer / demultiplexer switches for new and evolving, high-speed motherboard chipsets. These products provide configurable routing of high-speed differential signals to DisplayPort, PCIe, SAS/SATA, and USB connectors, and use innovative design techniques to minimize impedance, cross-talk, and skew to ensure optimal signal integrity.
