STA5635S General Description

The STA5635S is a fully integrated RF front-end able to support different bands (L1/E1, L2C, L5/E5/E6) thanks to a programmable and flexible RF-IF chain driven by a fractional PLL. In particular, STA5635S is able to manage all the GNSS constellations available and planned in the next future like GPS, Galileo, Glonass, BeiDou, IRNSS and QZSS.The RF_IF chain is followed from a 2-bit ADC able to convert the IF signal to Sign (SIGN) and Magnitude (MAG) bit. The MAG bit is internally integrated in order to control the variable gain amplifiers. The VGA gain can be also set by the SPI interface.The embedded fractional PLL allows supporting a wide range of reference clocks (10 to 55 MHz) and generates a sampling clock available for the baseband.The STA5635S embeds two LDOs to supply at 1.1 V the analog and digital cores of the device facilitating requirements to external power supply. A third LDO can be turned-on to supply at 1.8 V external active components as a TCXO.The chip is manufactured in CMOS040nm technology and housed in a QFN package.

Original Items, within tolerance, thank you.

I bought a lot of electronics for a mug of radio electronics and robotics, delivery is fast, everything looks great we will check with the guys during the school year.(Very comfortable weight, because. Young gifts sometimes connect the power to the wrong ports as a result of which everything glows warm and stops working, i hope that this device will help to solve the problem of burned ardules)
