L64014 PCMCIA Bridge
11
VS_N
Decoder Vertical Sync
Output
VS_N is the vertical sync signal to both the DVD Decoder
and the NTSC/PAL Encoder.
VVALID_N
Decoder Valid Video
Output
The L64014 asserts this signal in response to VREQ_N if
there is a valid data byte on the AD[8:0] bus. The L64020
inputs the byte when it deasserts VREQ_N.
WAIT_N
Decoder Wait
Input
The L64020 asserts WAIT_N to indicate that its Host Inter-
face is busy with a read or write bus cycle and deasserts
it when the current cycle is completed. WAIT_N is 3-stated
when CS_N is not active.
Zoomed Video Interface
ZVENABLE
Zoomed Video Enable
Input
When HIGH, this signal enables output to the Zoomed
Video Port.
ZVHREF_N
Zoomed Video Horizontal Reference
Output
This signal provides the horizontal sync signal to the
zoomed video port.
ZVHS_N
Zoomed Video Horizontal Sync
Output
ZVHS_N is the Zoomed Video horizontal sync.
ZVON
Zoomed Video On
Output
The L64014 drives this signal HIGH when the Zoomed
Video outputs are active. ZVON is LOW when the ZV
outputs are high impedance.
ZVPIXCLK
Zoomed Video Pixel Clock
Output
The operating frequency for this clock is selectable at
either 13.5 MHz or 27 MHz.
ZVUV[7:0]
Zoomed Video Chroma [7:0]
Output
This eight-bit output bus contains color chrominance
data.
ZVVREF_N
Zoomed Video Vertical Reference
Output
ZVVREF_N provides the vertical sync signal to the
zoomed video port.
ZVYUV[7:0]
Zoomed Video Luma [7:0]
Output
This eight-bit output bus contains color luminance data.
