Overview
The DS90C385AMTX/NOPB is a 3.3V programmable LVDS (Low Voltage Differential Signaling) transmitter designed by Texas Instruments. This component is part of the FPD-Link (Flat Panel Display Link) family and is specifically tailored for high-speed data transmission in flat-panel display applications. It is pin-to-pin compatible with the DS90C383, DS90C383A, and DS90C385, making it an ideal replacement for these models with additional features and improvements.

Key Features
- No special start-up sequence required between clock/data and /PD pins.
- Support for spread spectrum clocking up to 100kHz frequency modulation and deviations of ±2.5% center spread or -5% down spread.
- Input clock detection feature that pulls all LVDS pairs to logic low when the input clock is missing and the /PD pin is logic high.
- 18 to 87.5 MHz shift clock support.
- Programmable rising or falling edge strobe through a dedicated pin.
- Compliant to TIA/EIA-644 LVDS standard.
- Low profile 56-lead TSSOP package.
- Up to 2.45 Gbps throughput and up to 306.25 Megabyte/sec bandwidth.
- Supports VGA, SVGA, XGA, SXGA (dual pixel), SXGA+ (dual pixel), and UXGA (dual pixel) resolutions.
Applications
The DS90C385AMTX/NOPB is designed for use in various flat-panel display applications, including LCD monitors, TVs, and other high-resolution display systems. It is particularly useful for solving EMI and cable size problems associated with wide, high-speed TTL interfaces. The device can also be used as a replacement for other FPD-Link transmitters like the DS90CF583 and DS90CF581 with appropriate modifications.
