NIPPON PRECISION CIRCUITS—10

High-speed Conversion

For example, an NTSC signal interlace-to-noninter-

lace conversion. If interpolated line data can be

assumed to be similar to the preceding line data and

the write data rate is 14.3 MHz (4fSC), then conver-

sion can be realized by reading twice at 28.6 MHz

(8fSC).

Furthermore, interpolated line data, with appropriate

signal processing separation, can be read out line-by-

line by alternating between 2 SM5838AS devices (1

line/device).

In reality, however, double the number of devices are

required for luminance signal (Y) and color differ-

ence signal (C) systems. And triple the number of

devices are required for RGB signal systems.
