CXD2951GA-2 Single Chip GPS LSI Description The CXD2951GA-2 is a dedicated single chip LSI for the GPS (Global Positioning System), satellitebased location measurement system. This LSI enables the configuration of a single chip system providing a cost-effective, low-power solution. Compared with conventional methods, position detection time and sensitivity are substantially improved with the use of an advanced signal processing scheme. With the integration of both the Radio and baseband blocks into a single CMOS IC, the CXD2951GA-2 is ideal for use in automotive, cellular handset, handheld navigation, mobile computing and other location-based applications.

In this mode, the low power consumption can be achieved by stopping all oscillators except for RTC oscillator during the reset interval. Although all registers are initialized, the SRAM contents in backup area are held. In order to cancel this mode (reset cancellation), set EOSCEN high at first and then set EXRS high after the oscillation stabilization time and PLL lock time have passed. It needs 100ms or more. See Initialization section.

CXD2951GA-2 Initialization The CXD2951GA-2 is initialized by setting the reset signal EXRS (Pin 151) to the low level. Note that internal RAM is not initialized by the operation. Satisfy the conditions shown below for the timing and others. 1. When turning the power on (Power-on reset) VDD Power supply, EOSCEN (Pin 119) VDD [V] EXRS (Pin 151) 100ms or more VDD/2 GND The power supply both 3.3V and 1.8V should turn on simultaneously, and EOSCEN (Pin 119) should also rise simultaneously with the power supply turning on. EXRS (Pin 151) should rise 100ms or more after the power supply and EOSCEN rise. 2. Initialization during operation Power supply, EOSCEN (Pin 119) VDD EXRS (Pin 151) VDD [V] 100µs or more VDD/2 GND For initialization during operation, the interior circuit except internal RAM is initialized by setting the EXRS (Pin 151) signal to the low level for 100µs or more. Note that internal RAM is not also initialized by the operation. At this time, the EOSCEN (Pin 119) signal should keep the high level. – 18 – CXD2951GA-2 RTC crystal and TCXO In order to operate CXD2951GA-2 appropriately, the recommended characteristics of RTC crystal and TCXO is shown below.

The signal flow starts from the RFIN port (Pin 47). The signal is amplified and mixed down to the first Intermediate Frequency (IF) of 2MHz with cosine and sine wave quadrature mixers. Out of band images are filtered out and the signal is again mixed down to the 2nd IF of 1MHz with another set of quadrature mixers. The complex signal becomes real with the addition of real and imaginary components. The image of the 2nd IF mixing is removed with the last Band Pass Filter (BPF). The real signal is then amplified one last time and transferred to digital baseband processing unit.

The loop filters (RF and IF) are externally connected. Use parts that satisfy the required tolerance. – 20 – CXD2951GA-2 Radio Characteristics DC Characteristics Item Supply current 1 Supply current 2 (VDD = 1.8V, Ta = 25°C) Symbol IDD Conditions Active mode∗1 IPS Power save mode∗1 Min.
