12.15.1. General Description
The DS90C385 transmitter converts 28 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 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 85 MHz, 24 bits of RGB data and 3 bits of LCD timing and control data (FPLINE,
FPFRAME, DRDY) are transmitted at a rate of 595 Mbps per LVDS data channel. Using an 85 MHz
clock, the data throughput is 297.5 Mbytes/sec. Also available is the DS90C365 that converts 21 bits of
LVCMOS/LVTTL data into three LVDS (Low Voltage Differential Signaling) data streams. Both
transmitters 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/DS90CF366) without any translation logic.
The DS90C385 is also offered in a 64 ball, 0.8mm fine pitch ball grid array (FBGA) package which
provides a 44 % reduction in PCB footprint compared to the TSSOP package. This chipset is an ideal
means to solve EMI and cable size problems associated with wide, high-speed TTL interfaces.
