Hardware Description
The EVB-USB2514Q48 has one on board regulator, which generates 3.3V from 5V power supply. The
USB2514 generates is own on chip 1.8V supply. The USB2514 Hub consumes power from the 3.3V
supply while the MIC2026 Power distribution switch consumes power from the 5V supply. The
MIC2026 Power distribution switch supplies power to each down-stream port.
Down-stream ports are numbered 1 through 4 with individual port power controllers. The power
distribution switches are for power distribution and circuit protection to the downstream ports 1-4. Via
the EEPROM configuration, ports can be disabled, reordered, and polarity reversed in any order to
support multiple product SKUs and for optimal port routing see USB2514 datasheet for more detail.
Upstream and downstream port connector circuits are designed for USB 2.0 compliance with
decoupling, filtering, grounding and optional EMI/ESD circuitry.
The EVB-USB2514Q48 has been configured to support register settings loaded via the EEPROM as
determined by the state of CFG_SEL2, CFG_SEL1, CFG_SEL0 pins immediately after reset. The
internal 1.8V regulator supplies power to the oscillator and PLL, which is turned off during suspend to
minimize suspend current.
