SE4110L-R

SE4110L GPS Receiver IC Applications High sensitivity / low power GPS and A-GPS applications Portable navigation devices, mobile phones and GPS peripheral devices Telematics equipment 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. 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. 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.
