1.6.5 Winbond W83627HF-AW LPC Super I/O
The Winbond W83627F/HF is made to fully comply with Microsoft PC98 and PC99
Hardware Design Guide. Moreover, W83627F/HF is made to meet the specification of
PC98/PC99’s requirement in the power management: ACPI and DPM (Device Power
Management). Super I/O chip provides features as the following:
• Meet LPC Spec. 1.0
• Support LDRQ# (LPC DMA), SERIRQ (serial IRQ)
• Include all features of Winbond I/O W83977TF and W83977EF
• Integrate Hardware Monitor functions
• Compliant with Microsoft PC98/PC99 Hardware Design Guide.
• Support DPM (Device Power Management), ACPI
• Programmable configuration settings
• Single 24 or 48 MHz clock input
1.6.6 NS DS90C385 LVDS Transmitter
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 a 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.
