This datasheet provides detailed information about the X9520, including its features and specifications.
The X9520 integrates three Digitally Controlled Potentiometers, a power‑on‑reset circuit, two programmable voltage monitors and a 2 kbit EEPROM, all accessed via a 2‑wire serial interface. It is designed for bias and modulation control of laser diodes in GBIC fiber‑optic modules, reducing board space and improving reliability.
Key features include multiple DCP tap resolutions, write‑protect and block‑lock EEPROM, single‑supply operation from 2.7 V to 5.5 V, and a 20‑lead TSSOP package. The datasheet provides pinout diagrams, serial protocol details, and programming instructions for both volatile and non‑volatile operations.
