TPAFEA008

4-Channel EML Monitor and Controller with Positive/Negative Voltage and Current DAC

Overview

The TPAFEA008 is an integrated product with 4-ch negative/positive output VDAC and 4-ch IDAC, which is optimized for the optical module with 4-channel EML (Electro-absorption Modulated Laser).

The VDAC in TPAFEA008 supports both negative and positive output ranges, and the current capability is large enough to bias EAM (Electro-Absorption Modulator).

The IDAC in TPAFEA008 can support large output current range, and the output voltage range is also large enough to support different laser diodes.

The TPAFEA008 includes a 12bit ADC, with 4 input pins. Also, it incorporates internal alarm functions for ADC, so it can be used for RSSI (Received Signal Strength Indicator) and LOS (Loss of Signal) detection.

The VDAC output current and IDAC output voltage can be monitored by an integrated 12-bit ADC, so it is convenient for customers to monitor the loading status, without external components.

The TPAFEA008 is featured with small size, high integration, wide supply range, and operating temperature range, which make the device an excellent choice for 4-ch EML optical modules.
