PIN DESCRIPTION
NAME
FUNCTION
TTL LINK MON TTL Link Monitor output. Signal is
low when the VIN+, VIN– inputs
exceed the minimum threshold,
which is set by a voltage on the
VTHADJ pin. Signal is high when the
input signal level is below the
threshold. Capable of driving a 10mA
LED indicator. This pin can be tied to
CMP ENABLE.
CMP ENABLE
A low voltage at this TTL input pin
enables both the ECL and the TTL
outputs. A high TTL voltage disables
the comparator output with ECL+
high, ECL– low, and TTL OUT high.
VIN–
This input pin should be capacitively
coupled to the input source or to
filtered ground. (The input resistance
is approximately 1.6k
Ω.)
VIN+
This input pin should be capacitively
coupled to the input source or to
filtered ground. (The input resistance
is approximately 1.6k
Ω.)
ECL–
The ECL comparator negative output.
Has internal pull down resistor.
External pull downs are not required
unless driving a large capacitive
load.
ECL+
The ECL comparator positive output.
Has internal pull down resistor.
External pull downs are not required
unless driving a large capacitive
load.
GND TTL
The negative supply for the TTL
comparator stage. If the TTL output is
not necessary, connect GND TTL
to VCC.
NAME
FUNCTION
VCC TTL
The positive supply for the TTL
comparator stage. If the TTL output is
not necessary, connect VCC TTL to
VCC. (ML4624 only)
TTL OUT
TTL data output.
VDC
An external capacitor on this pin
integrates an error signal which nulls
the offset of the input amplifier. If the
DC feedback loop is not being used,
this pin should be connected to VREF.
CF2
A capacitor from this pin to CF1
controls the maximum bandwidth of
the amplifier.
CF1
Connect to CF2 through a capacitor.
GND
Negative supply. Connect to –5.2V
for ECL operation, or to ground for
TTL or raised ECL operation.
VTHADJ
This input pin sets the link monitor
threshold.
VREF
A 2.5V reference with respect to
GND.
CTIMER
A capacitor from this pin to VCC
determines the Link Monitor
response time.
VCC
Positive supply. Connect to ground
for negative ECL operation, or to 5V
for TTL or raised ECL operation.
