This is information on a product in full production. For further information contact your local STMicroelectronics sales office. September 2013 Doc ID 16055 Rev 4 1/8 8 STA5630 Low power GPS RF front-end Data brief  production data Features ■ Integrated LNA ■ Low power consumption (< 25 mW) ■ 1.8 V supply voltage ■ GPS and Galileo compliant ■ Minimum external components ■ Serial interface ■ 3 bits A/D converter ■ CMOS 65 nm technology ■ Standard QFN-32 package ■ Ambient temperature range: -40 °C to +85 °C Description The STA5630 is a fully integrated RF front-end able to down-convert either the GPS L1 signal from 1575.42 MHz to 4.092 MHz. The STA5630 embeds high performance LNA minimizing external component count. The chip uses state of the art CMOS 65 nm technology. A 3-bit ADC converts the IF signal to Sign (SIGN) and Magnitude (MAG0 and MAG1). The magnitude bits are internally integrated in order to control the variable gain amplifiers. The VGA gain can be also set by the SPI interface. The STA5630 accepts a range of reference clocks (10 to 52 MHz) and generates a 16.368 MHz sampling clock (GPS_CLK) for the baseband. The STA5630 embeds LDO to supply the internal core of the device facilitating requirements to external power supply. High performance, low power, and cost effective device, the STA5630 is the ideal solution for automotive, cellular and consumer battery powered applications. VFQFPN32 Table 1.

STA5630 Applications Doc ID 16055 Rev 4 3/8 1 Applications Three main applications cases are considered and described hereafter. The first uses a passive antenna and only a single RF SAW in front of the internal LNA. It targets low cost and medium performance applications. In this case LNA is ON and RFA could be set at minimum gain if heavy blocker signals are present. The second uses a passive antenna and two RF SAWs. It maximizes the performances in presence of severe blockers. In this case LNA is ON and RFA is set at maximum gain. The third case uses an active antenna. This solution targets applications where the GPS antenna is far from the RF front-end. In this case the signal can be fed into either LNA or RFA input depending on the application conditions. STA5630 is suitable for baseband requiring 16.368/4.092 clock/RF interface and one, two or three bits samples. It accepts reference clocks (TCXO) in the range of 10-52 MHz and delivers a TCXO buffered copy to the baseband. The STA5630 has two default modes selectable by an external pin (MODE): ● MODE 0: the chip is configured to use 16.368 MHz as reference frequency, ● MODE 1: the chip is configured to use 26 MHz as reference frequency. Other modes are programmed through the serial interface 1.1 Block diagram Figure 1. Block diagram
