PMB 2520 Hammerhead

The PMB 2520 Hammerhead is a IC sulution for GPS that producted by the Infineon Technologies. It allows the usage of assistance data by surpporting A-GPS standards.

Modules of the Hammerhead

The Hammerhead consists of the following modules:

  • RF front-end with on-chip, high gain and low noise, LNA, I/Q mixers, on-chip polyphase complex IF filter, digitally controlled AGC, and 3-bits ADC for the I and Q paths.
  • Sigma-Delta RF PLL with on-chip PCO and on-chip loop filter.
  • Embedded PLL and NCO for baseband clock generation.
  • Multiple channels digital mixers and parallel correlator engines to enable real time correlation of the PRN code for up to 14 satellites.
  • Post processor including peak detection logic
  • SRAM for storing correlation results
