BU8255KVT ROHM Co. Ltd., BU8255KVT Datasheet - Page 16

• Manufacturer Part Number: BU8255KVT
• Description: 35bit Lvds Receiver 5 35 Deserializer
• Manufacturer: ROHM Co. Ltd.

＊3 Recommended Parts：
＊4 :RS pin acts as VREF input pin when input voltage is set to half of high level signal input.
●10bit Small Swing Input & LVCMOS Level Output
Example:
BU8254KVT ： LVCMOS level input/Falling edge/LVDS normal(350mV) swing output
BU8255KVT ： LVCMOS level output/Falling edge
F.Bead ： BLM18A-Series （ Murata Manufacturing Co. ）
We recommend to locate by-pass condenser near the RS pin.
Example for LVTTL(1.8V input):(R1,R2)=(15kΩ,5.6kΩ)
