GPS Receiver IC

The SE4100L is an integrated GPs receiver designed to receive the L1 signal at 1575.420 MHz. The receiver has a low IF architecture and integrates all of the Amplifier Oscillator mixer and IF sampling functions. The high level of integration reduces the external component count to just 14 passives in addition to power supply de-coupling and a 16.368 MHz crystal. Furthermore, elimination of the need for an external VCO Resonator and RF Filter reduces the critical off-chip RF circuitry to just three matching components to achieve optimum noise match at the LNA input. Combined with the 4x4 mm LPCC package, this results in a very small circuit footprint with no need for electrical screening in many applications. The SE4100Ls small size and BOM requirement is complemented by just 35 mW typical operating power consumption. Digitally controlled shutdown modes enable the 16.368 MHz Clock signal to the baseband processor to be maintained separately from operation of the rest of the receiver. A switchable gain LNA enables the SE4100L to be used with either a local passive Antenna or with a remote active Antenna without changing the circuit configuration. An image reject mixer downconverts the RF signal to a 4.092 MHz IF. The integrated IF Filter feeds a combiner, limiter and output latch. The output signal is a 1-bit quantized 4.092 MHz digital IF.
