which also shows a typical OTG V
amount of current drive required. If the internal charge pump is not used, the C
capacitor is not required.
For details on the C_A and C_B pins, see
The band gap circuit provides a stable internal voltage reference to bias analog circuitry.
This band gap requires an accurate external reference resistor, R
between the RREF and GND pins. For details, see
The ISP1506 has an internal power-on-reset circuit that resets all internal logic on
power-up. The ULPI interface is also reset on power-up.
Remark: When CLOCK starts toggling after power-up, the USB link must issue a reset
command over the ULPI bus to ensure correct operation of the ISP1506.
Dual-edge bidirectional data bus. The USB link must drive DATA[3:0] to LOW when the
ULPI bus is idle. When the link has data to transmit to the PHY, it drives a nonzero value.
The data bus can be reconfigured to carry various data types, as given in
