Texas Instruments DS125BR401A Low-Power 12 Gbps 4-Lane Repeater With Equalization DS125BR401ANJYT

The DS125BR401A is a low-power, high-performance 12 Gbps 4-lane repeater designed for applications requiring advanced signal conditioning. It features a typical power consumption of 65 mW per channel and allows for the powering down of unused channels to further reduce energy usage. The device supports linear equalization, which is beneficial for link training in PCIe and SAS applications, and can handle input signals with a maximum loss of -24 dB. The repeater includes continuous time linear equalizers (CTLE) that provide up to +24 dB of high-frequency boost at 6 GHz, enabling it to recover signals from intersymbol interference (ISI) and fully closed input eyes. The output voltage can be adjusted between 700 mV and 1400 mV, and the device operates with a single supply voltage of either 2.5 V or 3.3 V. With an operating temperature range of -40¬8C to 85¬8C and a 4 kV HBM ESD rating, the DS125BR401A is suitable for a variety of environments. The device is packaged in a compact 54-terminal WQFN format, making it suitable for space-constrained designs. Programmable settings can be configured via SMBus, I2C, or an external EEPROM, facilitating easy integration into existing systems.
