  • 简介
  • 详情
 The S1315F8 is a small form factor GPS module solution intended for a broad range of OEM products, where fast and easy system integration and minimal development risk is required. The user only need to provide DC power of 3.0V ~ 3.6V and GPS signal; the S1315F8 will output navigation solution in standard NMEA-0183 protocol format.

The S1315F8 features 65 channel GPS receiver with fast time to first fix and improved -148dBm cold start sensitivity. The superior cold start sensitivity allows it to acquire, track, and get position fix autonomously in difficult weak signal environment. The receiver’s -165dBm tracking sensitivity allows continuous position coverage in nearly all application environments. The high performance search engine is capable of testing 8,000,000 time-frequency hypotheses per second, offering industry-leading signal acquisition and TTFF speed.

Measuring 13mm x 15mm, the S1315F8 contains integrated LNA, SAW filter, 0.5ppm TCXO, 65 channel positioning engine, RTC crystal, and low-leakage backup supply LDO regulator. The RF section has cascaded noise figure of 1.2dB, allowing passive antenna operation without extra external LNA.

The receiver is optimized for applications requiring high performance, low power, and low cost; suitable for a wide range of OEM configurations including mobile phone, PND, asset tracking, and vehicle navigation products.

The metal RF shielding provides protection and allows standard surface mount device pick-and-place process in fully automated assembly process; enabling high-volume, very cost-efficient production. The S1315F8 is available in tape-and-reel form.
