Description
The Broadcom LPD3035 is a mesa-structured, InGaAs-based PIN
photodiode oering high responsivity, low dark current, and low
capacitance for high-bandwidth, high-performance optical receiver
designs.
The LPD3035 is designed with extra bandwidth when compared with
typical photodiodes used in 25-Gb/s NRZ signaling. This extra bandwidth
enables the LPD3035 to work with 32-Gbaud PAM-4-type signals. The
extra bandwidth also helps to ensure the linear fidelity of the PAM-4
signaling is preserved and cleanly launched into a linear TIA channel.
Broadcom DLH Technology™ is applied to the semiconductor device
coatings (passivation, etc.) on the photodiodes to enable the die
themselves to act as the hermetic seal against GR-468-type environments.
