DIN0–
DIN28
Data Input[0:28]. Parallel data inputs. All pins internally pulled down to GND. Selected
edge of PCLKIN latches input data. Set BWS = low (24-bit mode) to use DIN0–DIN20
(RGB and SYNC). DIN21–DIN28 are not used in 24-bit mode. Set BWS = high (32-bit
mode) to use DIN0–DIN28 (RGB, SYNC, and two extra inputs).
6 6 PCLKIN Parallel Clock Input. Latches parallel data inputs and provides the PLL reference clock.
7, 30, 51 7, 26, 44 IOVDD
I/O Supply Voltage. 1.8V to 3.3V logic I/O power supply. Bypass IOVDD to GND with
0.1FF and 0.001FF capacitors as close as possible to the device with the smaller value
capacitor closest to IOVDD.

50, 61
— GND Digital and I/O Ground
9, 18, 39 — AGND Analog Ground
10, 42 8, 36 AVDD
1.8V Analog Power Supply. Bypass AVDD to AGND with 0.1FF and 0.001FF capacitors
as close as possible to the device with the smaller value capacitor closest to AVDD.
19, 62 16, 54 DVDD
1.8V Digital Power Supply. Bypass DVDD to GND with 0.1FF and 0.001FF capacitors as
close as possible to the device with the smaller value capacitor closest to DVDD.

29 25 AUTOS
Autostart Setting. Active-low power-up mode selection input requires external pulldown
or pullup resistors. Set AUTOS = high to power up the device with no link active. Set
AUTOS = low to have the MAX9259 power up the serial link with autorange detection
(see Tables 11 and 12).
32 27 MS
Mode Select. Control-link mode-selection input requires external pulldown or pullup
resistors. Set MS = low, to select base mode. Set MS = high to select the bypass mode.
33 28 CDS
Control-Direction Selection. Control-link-direction selection input requires external
pulldown or pullup resistors. Set CDS = low for FC use on the MAX9259 side of the
serial link. Set CDS = high for FC use on the MAX9260 side of the serial link.
34 29 PWDN
Power-Down. Active-low power-down input requires external pulldown or pullup
resistors.
35 30 RX/SDA
Receive/Serial Data. UART receive or I
2
C serial-data input/output with internal 30kI
pullup to IOVDD. In UART mode, RX/SDA is the Rx input of the MAX9259’s UART. In I
2
C
mode, RX/SDA is the SDA input/output of the MAX9259’s I
2
C master.
