3 / 8 page 3 ML4622, ML4624 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. |
