Pin Description
PIN
NAME
FUNCTION
1
LOS
Loss-of-Signal Output, Open Drain. The default polarity of LOS is high when the level of the input
signal is below the preset threshold set by the SET_LOS DAC. Polarity of the LOS function can be
inverted by setting LOS_POL = 0. The LOS circuitry can be disabled by setting the bit LOS_EN = 0.
2
MSEL
Mode-Select Input, TTL/CMOS. Set the MSEL pin or MODE_SEL bit (set by the 3-wire digital interface)
to logic-high for high-bandwidth mode. Setting MSEL and MODE_SEL logic-low for high-gain mode.
The MSEL pin is internally pulled down by a 75k
resistor to ground.
3, 6, 27, 30
VCCR
Power Supply. Provides supply voltage to the receiver block.
4
ROUT+
Noninverted Receive Data Output, CML. Back-terminated for 50
load.
5
ROUT-
Inverted Receive Data Output, CML. Back-terminated for 50
load.
7
VCCD
Power Supply. Provides supply voltage for the digital block.
8
DISABLE
Transmitter Disable Input, TTL/CMOS. Set to logic-low for normal operation. Logic-high or open
disables both the modulation and bias current. Internally pulled up by an 8k
resistor to VCCT.
9
SCL
Serial Clock Input, TTL/CMOS. This pin has a 75k
internal pulldown.
10
SDA
Serial Data Bidirectional Input, TTL/CMOS. Open-drain output. This pin has a 75k
internal pullup,
but it requires an external 4.7k
pullup resistor to meet the 3-wire digital timing specification. (Data
line collision protection is implemented.)
11
CSEL
Chip-Select Input, TTL/CMOS. Setting CSEL to logic-high starts a cycle. Setting CSEL to logic-low
ends the cycle and resets the control state machine. Internally pulled down by a 75k
resistor to
ground.
12, 15, 18,
21
VCCT
Power Supply. Provides supply voltage to the transmitter block.
13
TIN+
Noninverted Transmit Data Input, CML
Typical Operating Characteristics—VCSEL Driver (continued)
(VCC = 3.3V, TA = +25°C, unless otherwise specified. Figure 1 shows the typical setup used for measurements. Registers are set to
default values unless otherwise noted, and the 3-wire interface is static during measurements. For testing, the MODE_SEL bit was
used and the MSEL pin was left open.)
