The X9530 is a highly integrated laser diode bias controller which incorporates two digitally controlled Programmable Current Generators, temperature compensation with dedicated look-up tables, and supplementary EEPROM array. All functions of the device are controlled via a 2-wire digital serial interface.
The X9530 combines two programmable current generators, an integrated 6‑bit A/D converter, temperature compensation and a 2176‑bit EEPROM in a 14‑lead TSSOP package. All functions are accessed through a 2‑wire digital serial interface, allowing external or internal temperature sensing.
Key features include a maximum output current of +1.6 mA per generator, 8‑bit (256‑step) resolution, temperature range from –40 °C to +100 °C with 2.2 °C/step resolution, and block‑lock protected EEPROM for storing module data or custom lookup tables.
