Part Number : DS125BR401A
Function : Low-Power 12 Gbps 4-Lane Linear Repeater With Equalization
Package : WQFN 54 Pin Type
Maker : Texas Instruments
Pinouts : 
Description :
The DS125BR401A is an extremely low-power high-performance repeater/redriver designed to support four lanes carrying high speed interface up to 12 Gbps. The B-Side receiver's continuous time linear equalizers (CTLE) provide high frequency boost of up to +24 dB at 6 GHz (12 Gbps) and are capable of opening an input eye that is completely closed due to inter symbol interference (ISI) induced by interconnect medium such as backplane traces or twinaxial copper cables.
The programmable equalization allows maximum flexibility in the physical placement within the interconnect channel. The A-Side channel has a 10 dB linear equalizer and linear
output driver.
Features
1. Low 65-mW/Channel (Typ) Power Consumption, With Option to Power Down Unused Channels
2. Linear Equalization allows for Link Training in PCIe and SAS
3. Supports Out-of-Band (OOB) Signaling
