Overview
The DS90C365AMT/NOPB is a +3.3V programmable LVDS (Low Voltage Differential Signaling) transmitter designed by Texas Instruments. It is part of the FPD-Link (Flat Panel Display Link) family and is pin-to-pin compatible with the DS90C363, DS90C363A, and DS90C365. This device is an ideal replacement for these models, offering additional features and improvements.
The DS90C365A converts 21 bits of LVCMOS/LVTTL data into four LVDS data streams, along with a phase-locked transmit clock. It supports a wide range of display resolutions, including VGA, SVGA, XGA, and SXGA (dual pixel), and operates at a transmit clock frequency of up to 87.5 MHz.

Key Features
- No special start-up sequence required between clock/data and /PD pins. Input signals can be applied either before or after the device is powered.
- Supports Spread Spectrum Clocking up to 100kHz frequency modulation with ±2.5% center spread or -5% down spread.
- 18 to 87.5 MHz shift clock support.
- “Input Clock Detection” feature pulls all LVDS pairs to logic low when the input clock is missing and when the /PD pin is logic high.
- Programmable for Rising edge strobe or Falling edge strobe through a dedicated pin.
- Low power consumption: < 146 mW at 87.5 MHz, and < 37 μW in power-down mode.
- Backward compatible with DS90C365, DS90C363A, and DS90C363 in TSSOP 48-lead package.
Applications
The DS90C365AMT/NOPB is designed for use in various display applications, including:
- VGA, SVGA, XGA, and SXGA (dual pixel) displays.
- Flat Panel Displays (FPDs) requiring high-speed data transmission.
- Graphics and video systems where robust and reliable data transmission is critical.
- Replacement for DS90CF563 (5V, 65MHz) and DS90CF561 (5V, 40MHz) FPD-Link Transmitters with appropriate modifications.
