CXA3355ER

44 pin VQFN (Plastic)

Description

The CXA3355ER is an IC developed as a GPS RF

down converter. This IC realizes a reduction in the

number of external parts by integrating an LNA,

image rejection mixer, IF filter, PLL and VCO (L, C)

into a small package with low current consumption.

Features

• Includes all functions required for the GPS down

converter

• Low current consumption (active mode):

≈ 1MHz)

• Low current consumption (power save mode) < 1µA

• Total gain

≈ 100dB

• Total NF

≈ 4dB

• On-chip VCO and PLL

• Supports typical TCXO frequencies

(13MHz, 16.368MHz, 18.414MHz, etc.)

• On-chip LNA (LNA NF: 2.0dB)

• Image rejection mixer

• On-chip IF filter, and an external filter can be

connected as an option for further band narrowing.

• 1-bit IF output

• Antenna sense function
