FIN1032
3.3V LVDS 4-Bit High Speed Differential Receiver
General Description
Features
This quad receiver is designed for high speed interconnect
utilizing Low Voltage Differential Signaling (LVDS) technology. The receiver translates LVDS levels, with a typical differential input threshold of 100mV, to LVTTL signal levels.
LVDS provides low EMI at ultra low power dissipation even
at high frequencies. This device is ideal for high speed
transfer of clock and data.
s Greater than 400Mbs data rate
The FIN1032 can be paired with its companion driver, the
FIN1031, or any other Fairchild LVDS driver.
s Fail safe protection for open-circuit, shorted and terminated conditions
s 3.3V power supply operation
s 0.4ns maximum differential pulse skew
s 2.5ns maximum propagation delay
s Low power dissipation
s Power OFF protection
s Meets or exceeds the TIA/EIA-644 LVDS standard
s Pin compatible with equivalent RS-422 and LVPECL
devices
s 16-Lead SOIC and TSSOP packages save space

Note 3: All typical values are at TA = 25°C and with VCC = 3.3V.
Note 4: tSK(LH), tSK(HL) is the skew between specified outputs of a single device when the outputs have identical loads and are switching in the same direction.
Note 5: tSK(PP) is the magnitude of the difference in propagation delay times between any specified terminals of two devices switching in the same direction
(either LOW-to-HIGH or HIGH-to-LOW) when both devices operate with the same supply voltage, same temperature, and have identical test circuits.
Note 6: fMAX Criteria: Input tR = tF < 1 ns, VID = 300 mV, (1.05V to 1.35V pp), 50% duty cycle; Output duty cycle 40% to 60%, VOL < 0.5V, VOH > 2.4V.
All channels switching in phase.
Note A: All input pulses have frequency = 10MHz, tR or tF = 1ns
Note B: CL includes all probe and jig capacitances
