Product Description
The SE4100 is an integrated GPS receiver designed to
receive the L1 signal at 1575.42MHz. The receiver has
a low IF architecture, and integrates all of the amplifier,
oscillator, mixer and demodulation functions.
The external component count is low, requiring just a
16.368MHz crystal and 11 passive components in its
minimum configuration. This and the 24 pin LPCC
package result in a very small circuit footprint, which is
complemented by just 30mW operating power.
Two digitally controlled shutdown modes enable either
to part to be powered down entirely or for just the 16
MHz clock supply to the baseband processor to be
maintained.
A switchable gain LNA enables the SE4100 to be used
with a local passive antenna or with a remote active
antenna without changing the circuit configuration. The
on-chip VCO and PLL generates the required LO
frequency from the external 16.368MHz crystal. All of
the VCO and LO chain is integrated. An image reject
mixer downconverts the RF signal to a 4.092MHz 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 at CMOS levels.
