The DS1843 is a sample-and-hold circuit useful for capturing fast signals where board space is constrained. It includes a differential, high-speed switched capacitor input sample stage, offset nulling circuitry, and an output 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 Ethernet Passive Optical Network (GEPON) OLT
- Gigabit Passive Optical Network (GPON) OLT
- GPON Optical Network Unit
- Sample and Hold
