WIDE FREQUENCY BAND ANALOG SWITCH
DESCRIPTION
PIN CONFIGURATION (TOP VIEW)
The M52348SP is an semiconductor IC for RGBHV interface that
switches signals input from two types of image source and outputs
them to CRT display etc. The synchronous signal meets the
frequency band of 10 kHz to 200 kHz and is output with TTL. The
IC adopts 250 MHz for the frequency band width of video signal,
providing high resolution images. It is optimum as an IC for
interface with various types of new media including high resolution
CRT.

3. As in the case of GV1, ∆GV1, GV2 and ∆GV2, find GV3 and GV4.
Note) Omitted because the signal input pins and SW No. have been
described in the Electrical Characteristics Table. SWA shall take
side a unless otherwise noted.

placed on side b, take measurements in ampere meter A and
specify the value to be Icc1 (or ICC2).
1. The conditions shall be as provided in the Electrical
Characteristics Table. This measurement shall use active probe.
2. Assign SW17 to GND and input SG2 into pin 2 only. When this is
the case, specify the output amplitude of T.P.31 to be VOR1.
In the same manner, specify the output to be VOR2 with SG4
input.
VDC1, VDC2 Output DC voltage 1, output DC voltage 2
When SW17 is assigned to GND (or OPEN), and no signal is input,
measure T.P.31 (T.P.28, T.P.25) output DC voltage. Specify the

increasing the SG1 amplitude, read the amplitude of the input
signal when the output waveform of T.P.31 is strained. The value is
specified to be Vimax1. In the same manner, measure Vimax 1 in
FC3, FC4 Frequency characteristics 3, frequency
characteristics 4 (250 MHz)
In the same manner as finding FC1, ∆FC1, FC2 and∆FC2, find FC3
and FC4 in response to input signal SG5.

2. Assign SW17 to GND and input SG3 into pin
only. Measure
the output amplitude of T.P.31 at that time and specify the value
to be VOR3.
2. Assign SW17 to GND and input SG2 into pin 2 only. When this is
the case, read the amplitude of T.P.31 output and specify the
value as VOR1.
3. Assign SW17 to ONPEN, measure the output amplitude of T.P.31
at that time and specify the value to be VOR3'.
4. When this is the case, calculate crosstalk C.T.L1 between 2

CAUTIONS FOR USING THE IC

2. The H and V inputs are specified to be 5.0 VTTL.
3. Input signals into input pins at fully lowered impedance.
wiring shape on the board. Be careful for the following points.
• When inserting an output pull-down resistance, make wire
between the output pin and the resistance as short as possible.
• Make the load capacitance of output pins as small as possible.

4. The H and V output pins (pins
and ) are as shown in Figure
1. Resistance can be inserted into a portion between power
supplies to improve the rising speed. However, set the R value
to limit the current to 7.5 mA or less. In Figure 1, R is 2 kΩ or
more.
• Install the Vcc-GND bus controller capacitance near the pin.
• Vcc shall use a stable power supply. (Individual Vcc should use
an independent power supply.)
• Insertion of a resistance of several tens of Ω between the output
pin and the circuit at the next stage makes oscillation harder.
• GND should be as wide as possible. Basically, solid earth should

GND: Outputs signal from the INPUT 1 side.
OPEN: Outputs signal from the INPUT 2 side.
For switching by applying voltage as shown in Figure 3;

The applied voltage shall be less than Vcc.
