Trimble Colossus ASIC

Trimble’s Colossus RF ASIC is a tightly integrated, single-chip, double-conversion radio receiver with pseudo-baseband I and Q outputs. It includes a low-noise amplifier, a programmable frequency synthesizer for two reference clock frequencies (12.5 MHz or 13.0 MHz), two built-in baseband samplers, and power-down circuitry. Its on-chip, voltage-controlled oscillator (VCO) eliminates the need for external VCO components. The Colossus uses just 20 mW of power.
