43 Gb/s 2: 1 SELECTOR
Features
Maximum output rate in multiplexing mode: 43 Gb/s
Output amplitude: 0.9 Vpp
Single-ended inputs
General Description
The CI0086 is a 2: 1 selector operating at rates up to 43 Gb/s output. The I/O levels are
SCFL (VH: 0.0 V, VL: -0.9 V). The IC is fabricated using a 0.1-m InP HEMT process.
The CI0086 is provided in a hermetically-sealed package with V-connectors.
