## 800G PAM4 Electrical DSP

The Qualcomm Dragonfly™ CU100 DSP is a 4nm CMOS single-chip, low-power and low-latency PAM4 Active Electrical Cable (AEC) Digital Signal Processor (DSP) retimer. It is a 100G/lane device delivering high performance, high reliability interconnect for 800G AECs. The CU100 can also function as an 8x106.25 Gbps protocol agnostic retimer.

## Use Cases

- Active electrial cables (AEC)
- On-board electrical retimers

## Benefits

### Advanced DSP technology

A suite of advanced signal processing algorithms engineered to deliver exceptional Bit Error Rate (BER) performance with ultra-low power consumption

### Powerful diagnostic technology

Offers a powerful suite of diagnostic and monitoring tools designed to give end users complete visibility into link performance, by leveraging real-time analytics across electrical or optical links.

## Features

- Diagnostics and monitoring: FEC error, EYE, SNR, Host/Line Loopback
- Full XBAR to ease layout
- 100G with two generation backwards compatibility (50G PAM4 and 25G NRZ)
- Medium Reach (MR) capability
- PRBS Gen/Check
