MAX9263 Pin Description
PIN NAME FUNCTION
1–5 DIN[12:16]
Data Input [12:16]. Parallel data inputs with internal pulldown to GND. Encrypted when HDCP
is enabled (see Table 1).
6 PCLKIN Parallel Clock Input. Latches parallel data inputs and provides the PLL reference clock.
7, 30, 51 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 capacitor closest
to IOVDD.
8, 20, 31, 50,
61
GND Digital and I/O Ground
9, 18, 39 AGND Analog Ground
10, 42 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 capacitor closest to AVDD.
11 DIN17
Data Input 17. Parallel data input with internal pulldown to GND. Encrypted when HDCP is
enabled (see Table 1).
12 DIN18/HS
Data Input 18/HSYNC. Parallel data input with internal pulldown to GND. Use DIN18/HS for
HSYNC when HDCP is enabled (Table 1).
13 DIN19/VS
Data Input 19/VSYNC. Parallel data input with internal pulldown to GND. Use DIN19/VS for
VSYNC when HDCP is enabled (Table 1).
14 DIN20
Data Input 20. Parallel data input with internal pulldown to GND. DIN20 is not encrypted when
HDCP is enabled (see Table 1).
15, 16, 17 DIN[21:23]
Data Input [21:23]. Parallel data inputs with internal pulldown to GND. DIN[21:23] are not
used in 24-bit mode. Set BWS = high (32-bit mode) to use [DIN21:23]. Encrypted when
HDCP is enabled (Table 1).
19, 62 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 capacitor closest to DVDD.
21, 22, 23 DIN[24:26]
Data Input [24:26]. Parallel data inputs with internal pulldown to GND. DIN[24:26] are not
used in 24-bit mode. Set BWS = high (32-bit mode) to use [DIN24:26]. Encrypted when
HDCP is enabled (see Table 1).
24, 25 DIN[27:28]
Data Input [27:28]. Parallel data inputs with internal pulldown to GND. DIN[27:28] are not
used in 24-bit mode. Set BWS = high (32-bit mode) to use [DIN27:28]. DIN[27:28] are not
encrypted when HDCP is enabled (see Table 1).
26 SD
I
2
S Serial-Data Input with Internal Pulldown to GND. Disable I
2
S to use SD as an additional
control/data input latched on the selected edge of PCLKIN. Encrypted when HDCP is enabled.
27 SCK I
2
S Serial-Clock Input with Internal Pulldown to GND
28 WS I
2
S Word-Select Input with Internal Pulldown to GND
29
AUTOS
Active-Low Autostart Setting. AUTOS requires an external pulldown or pullup resistor. Set
AUTOS = high to power up the device with no link active. Set AUTOS = low to have the
serializer power up the serial link with autorange detection (see Tables 11 and 12).
32 MS
Mode Select. Control link mode-selection input requires an external pulldown or pullup
resistor. Set MS = low to select base mode. Set MS = high to select the bypass mode.
33 CDS
Control Direction Selection. Control link direct selection input requires external pulldown or
pullup resistor. Set CDS = low for UART connection of a FC as a control master. Set CDS =
high for peripheral connection as a control-channel I
2
C or UART slave.
