AGND
3
3, 4, 6, 9
S analog ground; must be at the same potential as pin DGND
DIN 4 7 I differential input; complementary to pin DINQ; DC bias level is set
internally at approximately 2.1 V
DINQ
5
8 I differential input; complementary to pin DIN; DC bias level is set
internally at approximately 2.1 V

6
11, 12
S analog supply voltage; must be at the same potential as pin VCCD
7 13 A input for connection of capacitor to set time constant of level detector
input filter (optional); the capacitor should be connected between
VCCA and pin CF
8 16 I PECL-compatible input; controls the output buffers,
pins DOUT and DOUTQ; when a LOW signal is applied, the output
buffers 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
STQ
9 17 O PECL-compatible status output of the input signal level detector;
when the input signal is below the user-programmed threshold level,
this output is HIGH; complementary to pin ST
ST 10 18 O PECL-compatible status output of the input signal level detector;
when the input signal is below the user-programmed threshold level,
this output is LOW; complementary to pin STQ
DGND
11 19, 20, 22, S digital ground; must be at the same potential as pin AGND
25
DOUTQ
12
23 O PECL-compatible differential output; this pin will be forced into a
HIGH condition when pin JAM is HIGH; complementary to pin DOUT
DOUT
13
24 O PECL-compatible differential output; this pin will be forced into a
LOW condition when pin JAM is HIGH; complementary to
pin DOUTQ
VCCD

S digital supply voltage; must be at the same potential as VCCA
15 29 O band gap reference voltage; typical value is 1.2 V; internal series
resistor of 1 kΩ
RSET
16
30 A input signal level detector threshold setting; nominal DC voltage is
VCCA − 1.5 V; threshold level is set by connecting an external resistor
between VCCA and pin RSET or by forcing a current into pin RSET;
default value for this resistor is 180 kΩ which corresponds with
approximately 4 mV (p-p) differential input signal
