A phase-locked transmit clock is transmitted in parallel with the data streams over a fifth LVDS link. Every cycle of the transmit clock 28 bits of input data are sampled and transmitted. At a transmit clock frequency of 65 MHz, 24 bits of RGB data and 3 bits of LCD timing and control data (FPLINE, FPFRAME, DRDY) are transmitted at a rate of 455 Mbps per LVDS data channel. Using a 65 MHz clock, the data throughput is 227 Mbytes/sec. The DS90C383B transmitter 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 Receiver (DS90CF386) without any translation logic. This chipset is an ideal means to solve EMI and cable size problems associated with wide, high speed TTL interfaces. Block Diagram Figure 1.

APPLICATIONS INFORMATION The DS90C383B are backward compatible with the DS90C383/DS90CF383, DS90C383A/DS90CF383A and are a pin-for-pin replacement. This device may also be used as a replacement for the DS90CF583 (5V, 65MHz) and DS90CF581 (5V, 40MHz) FPD-Link Transmitters with certain considerations/modifications: 1. Change 5V power supply to 3.3V. Provide this supply to the VCC, LVDS VCC and PLL VCC of the transmitter. 2. The DS90C383B transmitter input and control inputs accept 3.3V LVTTL/LVCMOS levels. They are not 5V tolerant. 3. To implement a falling edge device for the DS90C383B, the R_FB pin (pin 17) may be tied to ground OR left unconnected (an internal pull-down resistor biases this pin low). Biasing this pin to Vcc implements a rising edge device. TRANSMITTER INPUT PINS The TxIN and control input pins are compatible with LVCMOS and LVTTL levels. These pins are not 5V tolerant. TRANSMITTER INPUT CLOCK/DATA SEQUENCING The DS90C383B does not require any special requirement for sequencing of the input clock/data and PD (PowerDown) signal. The DS90C383B offers a more robust input sequencing feature where the input clock/data can be inserted after the release of the PD signal. In the case where the clock/data is stopped and reapplied, such as changing video mode within Graphics Controller, it is not necessary to cycle the PD signal. However, there are in certain cases where the PD may need to be asserted during these mode changes. In cases where the source (Graphics Source) may be supplying an unstable clock or spurious noisy clock output to the LVDS transmitter, the LVDS Transmitter may attempt to lock onto this unstable clock signal but is unable to do so due the instability or quality of the clock source. The PD signal in these cases should then be asserted once a stable clock is applied to the LVDS transmitter. Asserting the PWR DOWN pin will effectively place the device in reset and disable the PLL, enabling the LVDS Transmitter into a power saving standby mode. However, it is still generally a good practice to assert the PWR DOWN pin or reset the LVDS transmitter whenever the clock/data is stopped and reapplied but it is not mandatory for the DS90C383B. SPREAD SPECTRUM CLOCK SUPPORT The DS90C383B can support Spread Spectrum Clocking signal type inputs. The DS90C383B outputs will accurately track Spread Spectrum Clock/Data inputs with modulation frequencies of up to 100kHz (max.)with either center spread of ±2.5% or down spread -5% deviations. 8 Submit Documentation Feedback Copyright © 2004–2013, Texas Instruments Incorporated Product Folder Links: DS90C383B DS90C383B www.ti.com SNLS177G – APRIL 2004 – REVISED APRIL 2013 POWER SOURCES SEQUENCE In typical applications, it is recommended to have VCC, LVDS VCC and PLL VCC from the same power source with three separate de-coupling bypass capacitor groups.
