DS90C363B Datasheet +3.3V Programmable LVDS Transmitter

Manufacturer: Texas Instruments

General Description

The DS90C363B transmitter converts 21 bits of CMOS/TTL data into three LVDS (Low Voltage Differential Signaling) data streams.

A phase-locked transmit clock is transmitted in parallel with the data streams over a fourth LVDS link.

Every cycle of the transmit clock 21 bits of input data are sampled and transmitted.

Overview

DS90C363B www.ti.com SNLS179F – APRIL 2004 – REVISED APRIL 2013 +3.

Key Features

  • 1.
  • 23 No special start-up sequence required between clock/data and /PD pins. Input signal (clock and data) can be applied either before or after the device is powered.
  • Support Spread Spectrum Clocking up to 100kHz frequency modulation and deviations of ±2.5% center spread or.
  • 5% down spread.
  • "Input Clock Detection" feature will pull all LVDS pairs to logic low when input clock is missing and when /PD pin is logic high.
  • 18 to 68 MHz shift clock suppor.
