NAME
FUNCTION
20
CNTL2
Control Input 2 with Internal Pulldown to GND. Data is latched every RXCLKIN_ cycle (Figure 7).
CNTL2 is not available in 3-channel mode. Drive BWS high (4-channel mode) to use this input.
CNTL2 is mapped to DIN28.
22, 39
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.
23, 38
GND
Digital and I/O Ground
24, 37
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 smallest value capacitor closest to
IOVDD.
25
RX/SDA
Receive/Serial Data. UART receive or I2C serial-data input/output with internal 30kI pullup to
IOVDD. In UART mode, RX/SDA is the Rx input of the MAX9249’s UART. In I2C mode, RX/SDA is
the SDA input/output of the MAX9249’s I2C master.
26
TX/SCL
Transmit/Serial Clock. UART transmit or I2C serial-clock output with internal 30kI pullup to IOVDD.
In UART mode, TX/SCL is the Tx output of the MAX9249’s UART. In I2C mode, TX/SCL is the SCL
output of the MAX9249’s I2C master.
27
SSEN
Spread-Spectrum Enable. Serial link spread-spectrum enable input requires external pulldown or
pullup resistors. The state of SSEN latches upon power-up or when resuming from power-down
mode (PWDN = low). Set SSEN = high for Q0.5% spread spectrum on the serial link. Set SSEN =
low to use the serial link without spread spectrum.
28
LMN1
Line-Fault Monitor Input 1 (see Figure 3 for details)
30, 31
OUT-,
OUT+
Differential CML Output+/-. Differential outputs of the serial link.
33
LMN0
Line-Fault Monitor Input 0 (see Figure 3 for details)
34
LFLT
Line Fault. Active-low, open-drain line-fault output with a 60kI internal pullup resistor. LFLT = low
indicates a line fault. LFLT is high impedance when PWDN = low.
35
INT
Interrupt Output to Indicate Remote Side Requests. INT = low upon power-up and when PWDN =
low. A transition on the INT input of the GMSL deserializer toggles the MAX9249’s INT output.
36
DRS
Data-Rate Select. Data-rate range-selection input requires external pulldown or pullup resistors.
Set DRS = high for RXCLKIN_ frequencies of 8.33MHz to 16.66MHz (3-channel mode) or 6.25MHz
to 12.5MHz (4-channel mode). Set DRS = low for RXCLKIN_ frequencies of 16.66MHz to 104MHz
(3-channel mode) or 12.5MHz to 78MHz (4-channel mode).
40, 46
N.C.
Internally Not Connected. Connect to GND or leave unconnected.
41
BWS
Bus-Width Select. Input width selection requires external pulldown or pullup resistors. Set BWS =
low for 3-channel mode. Set BWS = high for 4-channel mode.
42
PWDN
Power-Down. Active-low power-down input requires external pulldown or pullup resistors.
43
CDS
Control Direction Selection. Control link direction selection input requires external pulldown or
pullup resistors. Set CDS = low for FC use on the MAX9249 side of the serial link. Set CDS = high
for FC use on the GMSL deserializer side of the serial link.
44
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.
