Description
General part information
DS3922 Series
The DS3922 high-speed current mirror integrates high-voltage devices necessary for monitoring the burst mode receive power signal in avalanche photodiode (APD) biasing and OLT applications. The device has two small and one large gain current mirror outputs to monitor the APD current. An adjustable current clamp limits current through the APD. The clamp also features an external shutdown. An integrated FET is also provided that can be used to quickly clamp the high-voltage bias to ground in the case of high optical input power. Integrated low-voltage FET circuits can be used to create buck, boost, and inverting DC-DC converters for efficient laser bias and EML bias applications.The DS3922 is available in a 24-pin TQFN package and operates over an extended -40°C to +95°C temperature range.Applications10G EPON10GPON OLTAvalanche Photodiode (APD) MonitoringEML BiasGPON OLT
