The automatic power control (APC) and laser modulation functions are controlled by four temperature-based look-up tables (LUT). The look-up table has a 10-bit Σ-Δ DAC output, and each output has an independent LUT with 72 data. The DS1876 monitors 6 analog channels: temperature, VCC, transmit power and bias current of each of the two laser drivers. The device also provides an I2C compatible interface for connecting to the host system.
The DS1876 operates from -40 ° C to + 95 ° C and is available in a 5mm x 5mm, 28-pin TQFN package.
Panasonic understands manufacturers` challenges in adapting to the demands of increasingly wider market segments. So Panasonic designed a common platform that incorporates jumper wire and radial solutions in both the high-density and high-speed arenas, and an expanded axial solution with built-in jumper wire flexibility.
