SE4110L GPS Receiver IC Applications Product Description The SE4110L is a highly integrated GPS receiver offering high performance and low-power operation in a wide range of low-cost applications. It is particularly well-suited to mobile phone and high sensitivity L1-band GPS and A-GPS systems. High sensitivity / low power GPS and A-GPS applications Portable navigation devices, mobile phones and GPS peripheral devices Telematics equipment The SE4110L includes an on-chip LNA and a low IF receiver with a linear AGC and 2-bit analogue-to-digital converter (ADC). The receiver incorporates a fully integrated image reject mixer so no SAW filter is required in many applications. There is also an on-chip IF filter. Features Single-conversion L1-band GPS radio with integrated IF filter Integrated LNA; 1.6 dB typ. noise figure Low RF system noise figure; 2.3 dB typ. Low 10 mA operating current with 2.7-3.3 V supply; 8 mA with internal LNA disabled Standby current <10 µA Fully Integrated PLL, compatible with 13, 16.368, 19.5 and 26 MHz reference frequencies 2-bit SIGN & MAG Digital IF output Integrated VCO and resonator I/O supply range extends down to 1.7 V 4 x 4 mm 24 pin QFN Pb-free, RoHS compliant and Halogen-free The SE4110L supports a wide range of reference frequencies, addressing both traditional GPS systems and emerging mobile phone applications. The synthesizer is highly integrated requiring only two passive components to implement an off-chip loop filter. The SE4110L is optimized for the lowest possible power consumption consistent with the very low external component count. The SE4110L incorporates current-controlled lowspurious output buffers which may optionally be run from a separate external supply to interface to low voltage systems. The buffers supply sufficient current to drive most baseband devices directly.
