The S1722R is a compact 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 S1722R will output navigation
solution in standard NMEA-0183 protocol format.
The S1722R 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 17mm x 22mm, the S1722R 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 S1722R is available in
tape-and-reel form.
