Pin Functions (continued)

I/O DESCRIPTION

NAME NO.

MODE 21 I, S

Mode select configuration input. Default operational mode will be strapped at start-up based on the MODE

input voltage when PDB transitions LOW to HIGH. Typically connected to voltage divider through external

pullup to VDD18 and pulldown to GND applying an appropriate bias voltage. See MODE for detail.

CLK_OUT/IDX 19 I/O, S

IDX pin sets the I2C pullup voltage and device address; connect to external pullup to VDD and pulldown

to GND to create a voltage divider. When PDB transitions LOW to HIGH, the strap input voltage is sensed

at the CLOCK_OUT/IDX pin to determine functionality and then converted to CLK_OUT. See I2C Interface

Configuration for detail. If CLK_OUT is used, the minimum resistance on the pin is 35 kΩ. If unused,

CLK_OUT/IDX may be tied to GND.

FPD-LINK III INTERFACE

DOUT- 13 I/O

FPD-Link III Input/Output pins. These pins must be AC-coupled. See 图 19 and 图 20 for typical

connection diagrams and 表 178 for recommended capacitor values.

DOUT+ 14 I/O

POWER AND GROUND

VDDD_CAP 26 D, P

A connection for internal analog regulator decoupling capacitor. Typically connected to 10-µF, 0.1-µF, and

0.01-µF capacitors to GND. Do not connect to an external supply rail. See Typical Application for more

details.

VDDDRV_CAP 15 D, P

A connection for internal analog regulator decoupling capacitor. Typically connected to 10-µF, 0.1-µF, and

0.01-µF capacitors to GND. Do not connect to an external supply rail. See Typical Application for more

details.

VDDPLL_CAP 10 D, P

A connection for internal analog regulator decoupling capacitor. Typically connected to 10-µF, 0.1-µF, and

0.01-µF capacitors to GND. Do not connect to an external supply rail. See Typical Application for more

details.

VDDD 25 P

1.8-V (±5%) Power Supply pin.

Typically connected to 1-µF and 0.01-µF capacitors to GND.

VDDDRV 16 P

1.8-V (±5%) Analog Power Supply pin.

Typically connected to 1-µF and 0.01-µF capacitors to GND.

VDDPLL 11 P

1.8-V (±5%) Analog Power Supply pin.

Typically connected to 1-µF and 0.01-µF capacitors to GND.

GND DAP G

DAP is the large metal contact at the bottom side, located at the center of the VQFN package. Connect to

the ground plane (GND).

LOOP FILTER

LPF1 9 P Loop Filter 1: Connect as described in Loop Filter Decoupling.

LPF2 12 P Loop Filter 2: Connect as described in Loop Filter Decoupling.

CLOCK INTERFACE and GPIO

GPIO_0 17 I/O, PD General-Purpose Input/Output pins. These pins can also be configured to sense the voltage at their

inputs. See Voltage and Temperature Sensing. At power-up these GPIO pins default to inputs with a 300

kΩ (typical) internal pulldown resistor. If unused, these pins may be left floating, however, it is

recommended to disable them by setting the GPIOx_INPUT_EN to 0. See GPIO Support for

programmability.

GPIO_1 18 I/O, PD

GPIO_2 27 I/O, PD General-Purpose Input/Output pins. At power-up these GPIO pins default to inputs with a 300 kΩ (typical)

internal pulldown resistor. If unused, these pins may be left floating, however, it is recommended to

disable them by setting the GPIOx_INPUT_EN to 0. See GPIO Support for programmability.

GPIO_3 28 I/O. PD

CLKIN 20 I

Reference Clock Input pin. If operating in Non Sync external clock mode, connect this pin to a local clock

source. If unused (other clocking modes), this pin may be left open. See 表 6 for more information on

clocking modes.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
