HL5567 100 Gb/s PAM4 Encoder

$3,295.00 – $6,595.00

Datasheet  | S-parameters

The HL5567 PAM4 Encoder, available as either matched pairs (opt. -M) or individual devices (opt. -U), is an impedance-matched broadband resistive summing network designed to combine two equal-amplitude 50 Gb/s NRZ data streams into a single 100 Gb/s PAM4 signal.

When driven with two equal-amplitude NRZ signals, the LSB signal appearing on the PAM4 output is attenuated by 6 dB relative to the MSB signal.

For more information on deployment applications see HYPERLABS Application Note AN-2022-005-1.

This product is part of our line of Broadband Pick-off Tees.
