substrate pin; must be at the same potential as pin AGND
for test purpose only; to be left open in the application
analog ground; must be at the same potential as pin DGND
differential input; complementary to pin DINQ; DC bias level is set
internally at approximately 2.1 V
differential input; complementary to pin DIN; DC bias level is set
internally at approximately 2.1 V
analog supply voltage; must be at the same potential as pin V
input for connection of capacitor to set time constant of level
detector input filter (optional); the capacitor should be connected
between V
PECL-compatible input (TTL compatible for the TZA3044B);
controls the output buffers pins DOUT and DOUTQ; when a LOW
signal is applied, the outputs will follow the input signal; when a
HIGH signal is applied, the output buffers will latch into LOW and
HIGH states respectively; when not connected, pin JAM is actively
pulled LOW
PECL-compatible status output of the input signal level detector
(TTL compatible for the TZA3044B); when the input signal is below
the user-programmed threshold level, this output is HIGH;
complementary to pin ST
PECL-compatible status output of the input signal level detector
(TTL compatible for the TZA3044B); when the input signal is below
the user-programmed threshold level, this output is LOW;
complementary to pin STQ
digital ground; must be at the same potential as pin AGND
PECL-compatible differential output; forced into a HIGH condition
when pin JAM is HIGH; complementary to pin DOUT
PECL-compatible differential output; forced into a LOW condition
when pin JAM is HIGH; complementary to pin DOUTQ
digital supply voltage; must be at the same potential as V
band gap reference voltage; typical value is 1.2 V; internal series
resistor of 1 k
input signal level detector programming; nominal DC voltage is

resistor between V
pin RSET; default value for this resistor is 180 k which
corresponds with approximately 4 mV (p-p) differential input signal
