General Description
The DS1843 is a sample-and-hold circuit useful for cap-
turing fast signals where board space is constrained. It
includes a differential, high-speed switched capacitor
input sample stage, offset nulling circuitry, and an out-
put buffer. The DS1843 is optimized for use in optical
line transmission (OLT) systems for burst-mode RSSI
measurement in conjunction with an external sense
resistor.
Applications
Gigabit Passive Optical Network (GPON) OLT
Gigabit Ethernet Passive Optical Network (GEPON) OLT
GPON Optical Network Unit
