GPS solution - Single-Chip GPS Baseband Processor
Overview
The PL-6315 implements complete baseband signal processing function for a Global Positioning System (GPS) receiver. It combines acquisition search engine, 48-channel, equivalent to 4,000k/sec time-frequency windows, 32-bit RISC, and related peripherals into a single ASIC. Higher level of integration, lower power consumption, and added functionality are achieved at reduced system cost. A complete small footprint GPS receiver can be designed using only the PL-6315, GPS down-converter, external memory, and few discrete components.The acquisition search engine is designed to provide fast acquisition of satellite signals, and the 48-channel can track up to 16 satellites simultaneously. Any channel may be initialized to receive WAAS or EGNOS signal. Each may be deactivated when not required to track full 16 satellites, reducing overall power consumption and processor load.
The processor section contains a high performance 32-bit RISC, interrupt controller, programmable memory I/O interface, serial I/O, parallel I/O, general purpose I/O, timer, real-time clock, SPI master and debug support unit.

USB to Serial Bridge Controller – PL2303
Overview
The PL-2303 USB-to-Serial Bridge Controller is a low cost and high performance single chip solution. It provides a simple and easy way to use bridge/connectivity between the Universal Serial Bus (USB) and Serial Port interface. With the advantage of USB port, users have the capability to utilize the peripheral with serial port interface in an easy-to-use environment such as plug and play & hot swap function. This single chip is designed for ideal connections to Cellular Phone, Digital Camera, Modems or ISDN terminal adapters with over 1Mbps data transfer rate. The PL-2303 device and software drivers are capable of providing a no-firmware-change feature that enable USB interface to be transparent to serial port peripherals with minimum modifications.Feature
