| MITSUBISHI ICs (Monitor) M52757FP WIDE BAND ANALOG SWITCH DESCRIPTION The M52757FP is a semiconductor integrated circuit for the RGB interface. The device features switching signals input from two types of image sources and outputting the signals to the CRT display,etc. The frequency band of video signals is 250MHz, acquiring high-resolution images, and are optimum as an interface IC with highresolution CRT display and various new media. It includes Sync-separator, Video-signal-detector, and Sync-on G detector (SOG-DET.). PIN CONFIGURATION (TOP VIEW) FEATURES * Frequency band width : R.G.B ...................250MHz * Input level : R.G.B...............................0.7Vp-p (Typ.) * Video signal-detector Responsive frequency............................... ~50MHz Input level............................................0.7Vpp (Typ.) Detected level......................................150mV (Typ.) (Measure bottom to DET.level) * Only the G channel is proveded with buffer video output. * It is possible to save the consumption current by stopping current supply to Pin 2,4,6,20,24,30,33,35 because SOG-DET can be operated with only Vcc5 (Pin 15) as power save mode. * Include Sync Separation,Video signal detector, and Sync-on G detector. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 VideoDET-Hold 16 V-DETout 17 SWITCH 18 Input1 (R) Vcc1 (R) Input1 (G) Vcc1 (G) Input1 (B) Vcc1 (B) Input2 (R) GND1 Input2(G) GND5 Input2 (B) SyncDET1 SyncDET2 S-DETout Vcc5 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 VCC2 (R) OUTPUT (R) GND2(R) Vcc2(G) OUTPUT(G) GND2 (G) Vcc2 (B) OUTPUT(B) CND2(B) G Buffer out Sync SEP in Sync SEP out Vcc3 V-DET in3 GND4 V-DET in2 Vcc4 V-DET in1 Outline: 36P2R-D RECOMMENDED OPERATING CONDITION APPLICATION Display monitor Suply voltage range Rated voltage 4.75~5.5V 5.0V BLOCK DIAGRAM Vcc2(R) OUTPUT(R) Vcc2(G) OUTPUT(G) Vcc2(B) OUTPUT(B) Sync SEP in G Buffer out (for Sync on G) Sync SEP out Vcc3 V-DET in 3 V-DET in 2 Vcc4 V-DET in 1 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 20 19 R G B G Sync sepa OR POWER SAVE Vcc(5V) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 SW GND : INPUT1 SW OPEN : INPUT2 Vcc1(R) INPUT1(R) INPUT1(G) Vcc1(G) INPUT1(B) Vcc1(B) INPUT2(R) INPUT2(G) INPUT2(B) SyncDET1 SyncDET2 S-DET OUT Vcc5 V-DET out VideoDET-Hold (1 / 5) MITSUBISHI ICs (Monitor) M52757FP WIDE BAND ANALOG SWITCH ABSOLUTE MAXIMUM RATINGS (Ta=25 C) Symbol Vcc Pd Topr Tstg Vopr Vopr' Sarge Parameter Supply voltege Power dissiption Operating temperature Storage temperature Recommended operating supply voltege Recommended operating supply voltege range Ratings 7.0 1068 -20~+85 -40~+150 5.0 4.75~5.5 +200 - Unit V mW C C V V V Electrostatic discharge THERMAL DERATING (MAXIMUM RATING) 1250 1068 1000 750 500 250 -20 0 25 50 75 85 100 125 150 AMBIENT TEMPERATURE Ta ( C ) (2 / 5 ) MITSUBISHI ICs (Monitor) M52757FP WIDE BAND ANALOG SWITCH ( 3 / 5) MITSUBISHI ICs (Monitor) M52757FP WIDE BAND ANALOG SWITCH (4 / 5) MITSUBISHI ICs (Monitor) M52757FP WIDE BAND ANALOG SWITCH ( 5 / 5) |
