Turbo PMAC Family Overview
The DSPGATE1 IC also has on-board software-configurable clock generation circuitry. It can generate
the servo and phase clocks for the entire Turbo PMAC system (only one IC will do this; the others will
accept these as inputs). It also generates the clock signals that drive its own circuitry: DAC, ADC, PWM
and PFM (pulse-frequency-modulation).

MACRO ICs
The Turbo PMAC has two types of ASICs that support communication over the MACRO ring, the open-
architecture high-speed real-time communications ring that Delta Tau developed to simplify connection
of distributed control hardware.
