- DC - 3.125 Gbps with low jitter, high interference immunity, low power operation
- Receive equalization reduces ISI jitter due to loss of media
- Send pre-emphasis lossy backplane drivers and cables
-
On-chip 100Ω input and output termination minimizes insertion and return losses, reduces component count, and reduces board space. The DS25BR101 eliminates on-chip input termination for added design flexibility.
- The ESD on the 7 kV LVDS I/O pin protects adjacent components
- Small 3mm x 3mm LLP-8 space-saving package

Both the DS25BR100 chip and DS25BR101 are single-channel, 3.125 Gbps LVDS buffers, high-speed signal transmission, optimized lossy FR-4 printed circuit boards, backplanes, and balanced metal cables. Fully differential signal path for excellent signal integrity and noise immunity.
The DS25BR100 chip transmits pre-emphasis (PE) and receive equalization (EQ) with the DS25BR101 features, making them ideal for use as repeaters. Other LVDS devices with similar IO characteristics include the following products. The DS25BR120 features an optimized drive that uses four levels of pre-emphasis, while the DS25BR110 features four levels of equalization used as an optimized receiver. The DS25BR150 is a buffer/repeater with minimal power consumption and features that do not transmit pre-emphasis and do not receive equalization.
The wide input common-mode range can accept LVDS, CML, and LVPECL level signals at the output level of the receiver at LVDS. A very small package size requires minimal space on the board, and the pins flowing through allow the design of the board to be easier. The differential inputs and outputs of the DS25BR100 chip are internally terminated with a 100Ω resistor to reduce return loss, component count, and further board space. To increase design flexibility, the DS25BR101's 100Ω input terminal has been phased out. This puts an end to designing custom interconnects topologies and layout adjustments.
