APD20E1
28 Gbd Top-side Illuminated APD
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, 25G EPON and 50G PON.
This product features a Y-shaped pad configuration that is optimized for wire-bonding. The small chip footprint saves valuable space in small packages such as TO-headers.
