ZLNB2009 Overview
Key Specifications
Package: SSOP
Pins: 20
Operating Voltage: 5 V
Max Voltage (typical range): 10 V
Key Features
- T h e tw o pol a ri s at i on c ont r ol i nput s o f t h e ZLNB2006/09/10 have a nominal threshold of 14.75V
- The threshold is temperature compensated to minimise drift
- To ease design for this situation, each polarisation input of the ZLNB2009/10 has a second threshold set at 9.5V
- An input voltage below this threshold indicates “receiver not present”, switching the relevant control channels high
- This logic output can be used to disable the associated downfeed driver, eliminating any problems due to cable mismatch
