M52758SP/FP
WIDE BAND ANALOG SWITCH
DESCRIPTION
PIN CONFIGURATION(TOP VIEW)
The M52758 is a semiconductor integrated circuit f or the RGBHV
interf ace. The dev ice f eatures switching signals input f rom two
ty pes of image and outputting them to CRT display etc.
Sy nchronous signal meeting the f requency band of 10 kHz to
200 kHz are output at TTL. The f requency band of v ideo signals
is 250MHz, acquiring high-resolution images,and are optimum as
an interf ace IC with high-resolution CRT display and v arious new
media.

WIDE BAND ANALOG SWITCH
ELECTRICAL CHARACTERISTICS TEST METHOD (Pin No is FP)
It omits the SW.No accorded with signal input pin because it is already
written in Table .
SW A,SW1,SW3,SW5 is in side a if there is not defined specially.
Icc1,Icc2,Circuit current(no signal)
The condition is shown as Table . Set SW19 to GND(or OPEN) and SW A
to side b, measure the current by current meter A. The current is as
Icc1(Icc2).
VDC1,VDC2 Output DC voltage
Set SW19 to GND (or OPEN), measure the DC voltage of
T.P.35(T.P.30,T.P.27) when there is no signal input.The DC voltage is as
VDC1(or VDC2).
VDC3,VDC4 Output DC voltage
Measure the DC voltage of T.P.25 same as Table, the DC voltage is as
VDC3(or VDC4).
Vimax1,Vimax2 Maximum allowable Input
Set SW19 to GND, SG1 as the input signal of Pin 2.Rising up the
amplitude of SG1 slowly, read the amplitude of input signal when the output
waveform is distorted. The amplitude is as Vimax1. And measure Vimax1
when SG2 as the input signal of Pin 5,Pin 7 in same way. Next, set SW to
OPEN, measure Vimax2 when SG2 as the input signal of Pin11, 13, 16.
Gv1, Gv1,GV2, GV2
1. The condition is shown as Table .
2. Set SW19 to GND, SG2 as the input signal of Pin 2. At this time, read the
amplitude output from T.P 35. The amplitude is as VOR1.
3. Voltage gain Gv1 is
GV 1= 20 LOG VO R 1 [Vp-p] [dB]
0.7 [Vp-p]
4. The method as same as 2 and 3, measure the voltage gain Gv1 when
SG2 as the input signal of Pin 5, 7.
5. The difference of each channel relative voltage gain is as Gv1.
6. Set SW19 to OPEN, measure Gv2, Gv12 in the same way.
Gv3,Gv4,Voltage gain
1. The condition is shown as Table . This test is by active probe.
2. Measure the amplitude output from T.P.25.
3. Measure the GV3,GV4 by the same way as Gv1, Gv1,Gv2, Gv2.
Fc1, Fc1,Fc2, Fc2

2. Set SW19 to GND, SG2 as the input signal of Pin 2. Measure the
amplitude output from T.P.35.The amplitude is as VOR1.By the same way,
measure the output when SG4 is as input signal of Pin 2, the output is as
VOR2.
3. The frequency characteristic Fc1 is
VO R2 [Vp-p]

C.T.I.2 = 20 LOG VO R4'[Vp-p] [dB]
VO R4[Vp-p]
9. By the same way, measure the crosstalk between channels when SG3
as the input signal of Pin 13,16.
C.T.I.3,C.T.I.4 Crosstalk between two input
Set SG4 as the input signal, and then the same method as Table, measure
C.T.I.3, C.T.I.4.
C.T.C.1,C.T.C.2 Crosstalk between channel
1. The condition is as Table .This test is by active prove.
2. Set SW19 to GND, SG3 as the input signal of Pin 2. Measure the
amplitude output from T.P.35. The amplitude is as VOR5.
3. Next, measure T.P.30, T.P.27 in the same state, and the amplitude is as
VOG 5, VOB 5.
4. The crosstalk between channels C.T.C.1 is
