We proudly announce the launch of the SHF C684 A, the latest advancement in our series of analog Finite Impulse Response (FIR) filter equalization modules. Building upon the robust foundation of the SHF C683 A, the new SHF C684 A Feed-Forward Equalizer (FFE) is engineered to handle PAM4 signals at symbol rates up to 100 GBaud, equating to data rates of 200 Gbps.
Measured 80 GBaud (160 Gbps) input and output signal of a SHF C684 A
The SHF C684 A retains the hallmark features of its predecessor
- Frequency response to be arbitrarily modified by adjusting the filter coefficients (i.e. the gain of the tap amplifiers)
- Compact device to be placed wherever adaptive equalization is required e.g. close to the DUT at transmit or receive side
- Differential or single-ended mode
- Full compatibility with our proprietary SHF-Optimizer software
(Enabling precise calculation of filter coefficients based on imported signal traces or s-parameter files, and offering accurate predictions of output eye diagrams, frequency responses, and group delays.)
Key enhancements in the SHF C684 A
- Extended bandwidth for data rates even up to 200 Gbps
- Enhanced signal integrity to ensure clearer output signals
| C683 A | C684 A | |
| Maximum Analog Bandwidth | 55 GHz | 70 GHz |
| 1 dB Compression (Input) | 350 mV | 350 mV |
| Number of Taps | 6 | 5 |
