Amplifier and VCSEL Driver
Typical Operating Characteristics—VCSEL Driver (continued)
(V CC = 3.3V, T A = +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 RATE_SEL bit was
used and the RSEL pin was left open.)

NAME
LOS

FUNCTION
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.
Mode-Select Input, TTL/CMOS. Set the RSEL pin or RATE_SEL bit (set by the 3-wire digital interface)
to logic-high for high-bandwidth mode. Setting RSEL and RATE_SEL logic-low for high-gain mode.
The RSEL pin is internally pulled down by a 75k
resistor to ground.
Power Supply. Provides supply voltage to the receiver block.

DISABLE
Power Supply. Provides supply voltage for the digital block.
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 V CCT .

SCL
Serial-Clock Input, TTL/CMOS. This pin has a 75k
internal pulldown.
Serial-Data Bidirectional Input, TTL/CMOS. Open-drain output. This pin has a 75k
internal pullup,

SDA
but it requires an external 4.7k
pullup resistor to meet the 3-wire digital timing specification. (Data
line collision protection is implemented.)
Chip-Select Input, TTL/CMOS. Setting CSEL to logic-high starts a cycle. Setting CSEL to logic-low

CSEL
ends the cycle and resets the control state machine. Internally pulled down by a 75k
resistor to
ground.
