APD20E1
28 Gbd Top-side Illuminated APD
Top-side illuminated, ultra high-speed avalanche photodiode (APD) chip. A key feature of this innovative APD is a large dynamic range. The APD chip provides low noise multiplication and a high gain-bandwidth product which enables the design of high sensitivity 25G receivers. Typical applications include 28 Gbaud PAM-4, 100GBASE-ER4 and 25G EPON.
The Y-shaped contact pad layout is optimized for wire-bonding. The small chip footprint saves valuable space in small packages such as TO-headers.
