current input; connect the anode of PIN diode to this pin; DC bias level is
800 mV, one diode voltage above ground
analog ground
analog ground
bandwidth control pin; default bandwidth is 470 MHz; a resistor should be
connected between V
between BWC (pin 10) and AGND to increase bandwidth
substrate pin; to be connected to AGND
digital ground
test pin; not used in application; not connected
output select pin; when OUTSEL is HIGH, CML data outputs are active and
PECL data outputs are disabled; OUTSEL is pulled LOW if left unconnected,
PECL data outputs will then be active and CML data outputs disabled
digital ground
digital supply voltage
CML data output; OUTCML goes HIGH when current flows into IPhoto (pin 7)
CML compliment of OUTCML (pin 18)

PECL-compatible LOS detection pin; LOS output is HIGH when the input signal
is below the user programmable threshold level
PECL compliment of LOS
CMOS-compatible LOS detection pin; the LOSTTL output is HIGH when the
input signal is below the user programmable threshold level
pin for setting input threshold level; nominal DC voltage is V
threshold level set by connecting an external resistor between LOSTH and
V
analog ground
AGC monitor voltage; the internal AGC circuit can be disabled by applying an
external voltage to this pin
