DS90C365AMT

Product Summary

The DS90C365AMT is a 3.3V Programmable LVDS Transmitter. The DS90C365AMT converts 21 bits of LVCMOS/ LVTTL data into four LVDS (Low Voltage Differential Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams over the fourth LVDS link. The DS90C365AMT can be programmed for Rising edge strobe or Falling edge strobe through a dedicated pin. A Rising edge or Falling edge strobe transmitter will interoperate with a Falling edge strobe FPDLink Receiver without any translation logic. The DS90C365AMT is an ideal means to solve EMI and cable size problems associated with wide, high-speed TTL interfaces with added Spead Spectrum Clocking support.
