Operating Parameters
The PXS20 operating parameters are listed as follows:
•
•
•
•
•
Operating range 0 – 120 MHz
–40 to +105 °C ambient temperature
Fabricated in 90 nm low power process
1.2 V internal logic
Internal voltage regulator (VREG) with integrated ballast transistor
— Single-supply designs offering high integration level to the customer
3.3 V ±10% for digital I/O input supply voltage
Low power design
•
•
— Dynamic clock gating of core and peripherals
— Software controlled clock gating of peripherals
— Power consumption less than 400 mA
Selectable current slew rate (slow/medium/fast)
3.3 V ± 10% Nexus pin rail. Same as digital I/O rail
Unused pins configurable as GPIO or GPI for unused A/D channel inputs
3.3–5 V ±10% for A/D converter reference and analog input pins
Designed with EMI reduction techniques
— Phase-locked loop (PLL)
