EVALUATION KIT AVAILABLE DS3923 High-Speed Current Mirror with Sample/Hold Output General Description Benefits and Features The DS3923 high-speed current mirror integrates high- Accurate Burst-Mode RSSI Measurement with Two voltage devices necessary for monitoring the burst-mode Current Mirror Outputs Improves Dynamic Range receive power signal in avalanche photodiode (APD) bias- -32dBm to -5dBm Optical Input Range ing and optical line terminal (OLT) applications. It provides 0.5dB Accuracy small and large gain current mirror outputs to monitor the Sampling Period as Short as 300ns APD current. A sample/hold circuit with automatic gain selection captures the sampled signal so that an external Pin Discharge Option ADC can accurately measure the signal. An adjustable Low-Noise APD Bias with Shutdown Options current clamp limits current through the APD. The clamp Reduces Receiver Sensitivity also features an external shutdown. An integrated FET is also provided which can be used to quickly clamp the 15V to 76V APD Bias high-voltage bias to ground in the case of high optical External Capacitor Connection for Controlled RC input power. Time Constant of APD Voltage Filter The DS3923 is available in a 24-pin TQFN package and Current Clamp with Adjustable Limit and External operates over an extended temperature range of -40C Shutdown with Limit Status to +95C. High-Voltage Switch FET for APD Fast Shutdown Applications Small Package Reduces Total Solution Size and Cost APD Monitoring 3.5mm x 3.5mm, 24-Pin TQFN Package with GPON OLT Exposed Pad 10GPON OLT For related parts and recommended products to use with this part, refer Ordering Information appears at end of data sheet. to www.maximintegrated.com/DS3923.related.
