The DS125DF1610 is a sixteen-channel multi-rate retimer with integrated signal conditioning features. The device includes a fully adaptive Continuous Time Linear Equalizer (CTLE), Decision Feedback Equalizer (DFE), clock and data recovery (CDR), and a transmit FIR filter to enhance the reach and robustness over long, lossy, crosstalk impaired high speed serial links to achieve BER < 1×10-15.
Each channel of the DS125DF1610 independently locks to serial data at 9.8 to 12.5 Gbps and the divide by 2, 4 and 8 sub-multiples. A simple external oscillator (±100ppm) that is synchronous or asynchronous with the incoming data stream is used as a reference clock. Integrated 4x4 cross point switches allow for full non-blocking routing or broadcasting within each quad of the DS125DF1610.
Programmable transmit FIR filter offers control of the pre-cursor, main tap and post-cursor for transmit equalization. The fully adaptive receive equalization (CTLE and DFE) enables longer distance transmission in lossy copper interconnects and backplanes with multiple connectors.
A non-disruptive mission mode eye-monitor feature allows link monitoring internal to the receiver. The built-in PRBS generator and checker compliment the internal diagnostic features to complete standalone BERT measurements. Built-in JTAG enables manufacturing tests.

DS125DF1610EVM — 9.8 至 12.5 Gbps 16 通道重定時器評估模組
DS125DF1610EVM 可輕鬆評估 DS125DF1610。 使用者需要透過 SMA 連接器，為 EVM 提供電源和高速流量。低成本板載振盪器可為 DS125DF1610 的 PPM 計數器提供參考時脈，因此不需要外部時脈設備。
垂直 SMA 連接器提供與 DS125DF1610 中四路 2 的高速傳輸和接收端子的連接。如此可讓使用者評估裝置的接收和傳輸訊號條件功能，以及 4x4 類比交叉點開關。
使用者可以透過 SMBus 埠和 GUI 軟體來評估其他功能，例如，整合式眼開監測器 (EOM)、模式產生器、PRBS 檢查器和其他暫存器功能。
