Top-side illuminated, ultra high-speed avalanche photodiode (APD) chip. Key features of this innovative APD are a large dynamic range and a high optical damage threshold of up to +5 dBm. The APD chip provides low noise multiplication and a high gain-bandwidth product which enables the design of high sensitivity 28G receivers. Typical applications include 28 Gbaud PAM-4, 100GBASE-ER4 and 25G EPON.
This product features Y-shaped or G-S-G pad configurations that are optimized for wire-bonding. The small chip footprint saves valuable space in small packages such as TO-headers.
