PIN | TYPE(2) | DESCRIPTION | |
---|---|---|---|
NAME(1) | NO. | ||
FPD-LINK II SERIAL INTERFACE | |||
RIN+ | 33 | I | CML, inverting and noninverting differential inputs. The inputs must be AC-coupled with a 100-nF capacitor. |
RIN– | 34 | I | CML, inverting and noninverting differential inputs. The inputs must be AC-coupled with a 100-nF capacitor. |
CMF | 35 | I | Analog, common mode filter pin for the differential inputs. CMP is the virtual ground of the differential input stage. A bypass capacitor is connected from CMP to ground to increase the receiver’s common mode noise immunity. TI recommends a 4.7-µF ceramic capacitor. |
CMLOUT+ | 37 | O | CML, inverting and noninverting differential outputs. Single 100-Ω (1%) termination resistor must be placed across the CMLOUT± pins. Optional loop-through output to monitor post equalizer and requires use of the Serial Control Bus to enable. |
CMLOUT– | 38 | O | CML, inverting and noninverting differential outputs. Single 100-Ω (1%) termination resistor must be placed across the CMLOUT± pins. Optional loop-through output to monitor post equalizer and requires use of the Serial Control Bus to enable. |
MIPI INTERFACE | |||
DATA1+ | 19 | O | DPHY, inverting and noninverting data output of DPHY Lane 1. |
DATA1– | 18 | O | DPHY, inverting and noninverting data output of DPHY Lane 1. |
DATA0+ | 16 | O | DPHY, inverting and noninverting data output of DPHY Lane 0. |
DATA0– | 15 | O | DPHY, inverting and noninverting data output of DPHY Lane 0. |
CLK+ | 13 | O | DPHY, inverting and noninverting half-rate DPHY clock lane. |
CLK– | 12 | O | DPHY, inverting and noninverting half-rate DPHY clock lane. |
CONTROL AND CONFIGURATION | |||
PDB | 30 | I | LVCMOS with pulldown, power down mode input; PDB = 1, Device is enabled (normal operation), PDB = 0, Device is in power-down, When the device is in the power-down, outputs are TRI-STATE, control registers are RESET. |
CONFIG[1:0] | 10, 11 | I | LVCMOS with pulldown, operating mode select; CONFIG[1:0] selects compatibility to FPD-Link II serializers. See Table 1. |
EQ[3:1] | 1, 2, 3 | I | LVCMOS with pulldown, receive equalization control; EQ[3:1] provides 8 combinations of the receive equalization gain settings. See Table 2. EQ[3:1] optimizes the input equalizer’s ability to reduce inter-symbol interference from the loss characteristics of different cable lengths. |
BISTEN | 29 | I | LVCMOS with pulldown, BIST enable input; BISTEN = 1, BIST is enabled, BISTEN = 0, BIST is disabled. |
LOCK | 24 | O | LVCMOS, LOCK status output; LOCK = 1, PLL acquired lock to the reference clock input; DPHY outputs are active LOCK = 0, PLL is unlocked |
PASS | 25 | O | LVCMOS, normal mode status output pin (BISTEN = 0); PASS = 1: No fault detected on input display timing, PASS = 0: Indicates an error condition or corruption in display timing. Fault condition occurs if: 1) DE length value mismatch measured once in succession, 2) VSync length value mismatch measured twice in succession, BIST mode status output pin (BISTEN = 1); PASS = 1: No error detected, PASS = 0: Error detected. |
CCI AND I2C SERIAL CONTROL BUS | |||
SCL | 6 | I | LVCMOS open drain, serial control bus clock input, SCL requires an external pullup resistor to VDDIO. |
SDA | 5 | I/O | LVCMOS open drain, serial control bus data input and output, SDA requires an external pullup resistor to VDDIO. |
ID[1:0] | 8, 9 | I | LVCMOS with pulldown, serial control bus device ID address select, see Table 6. |
RESERVED PINS | |||
GPIO | 21 | I/O | General purpose I/O; Pin must be left floating during initial power-up. |
RES | 28 | I | LVCMOS with pulldown, reserved pin (must tie low) |
POWER AND GROUND | |||

VDDA | 31, 39 | P | Power to analog circuitry, 1.8 V ±5% |
VDDP | 40 | P | Power to PLL, 1.8 V ±5% |
VDDCSI | 20 | P | Power to DPHY CSI-2 drivers, 1.8 V ±5% |
VDDIO | 23 | P | Power to LVCMOS I/O circuitry, 1.8 V ±5% or 3.3 V ±10% (VDDIO) |
GND | 4, 14, 17, 22, 27, 32, 36 | G | Ground return |
GND | DAP | G | DAP is the metal contact at the bottom side, located at the center of the WQFN package. It must be connected to the GND plane with multiple via to lower the ground impedance and improve the thermal performance of the package. Connected to the ground plane (GND) with at least 9 vias. |
