7.9.7 C_A and C_B
Resistor reference analog I/O pin. A resistor, R
and GND, as shown in
biases internal analog circuitry. Less accurate resistors cannot be used and will render the
ISP1507 unusable.
DP (data plus) and DM (data minus) are USB differential data pins. These must be
connected to the D+ and D pins of the USB receptacle.
For OTG implementations, the ID (identification) pin is connected to the ID pin of the
micro-USB receptacle. As defined in On-The-Go Supplement to the USB 2.0 Specification
Rev. 1.3 , the ID pin dictates the initial role of the link. If ID is detected as HIGH, the link
must assume the role of a peripheral. If ID is detected as LOW, the link must assume a
host role. Roles can be swapped at a later time by using HNP.
If the ISP1507 is not used as an OTG PHY, but as a standard USB host or peripheral PHY,
the ID pin must be connected to REG3V3.
CPGND indicates the analog ground for the on-board charge pump. CPGND must always
be connected to ground, even when the charge pump is not used.
The C_A and C_B pins are to connect the flying capacitor of the charge pump. The output
current capability of the charge pump depends on the value of the capacitor used, as
shown in
For details, see
If the charge pump is not used, C_A and C_B must be left floating (not connected).
