MITSUMI Video Signal Driver for DVD Players MM1566 Video Signal Driver for DVD Players Monolithic IC MM1566 October 25, 2001 Outline This IC is a video signal driver IC that supports 3-ch interlace video developed for DVD players. It includes a low-pass filter that attenuates the noise element during DA conversion, and a 3-channel 6dB amp with 75Ω driver. In addition, external ESD protection diodes can be reduced by a sag correction pin for reducing output coupling capacitance, and enhancement ot the ESD protection elements for the output pins. Features 1. Includes a SAG correction pin. 2. Enabled to drive a 3-channel 6dB amp with 75Ω driver 3. Includes a 4th-order low-pass filter Frequency response: 6.75MHz ± 1dB / 27MHz – 27dB min. 4. Includes a 6dB amp 5. Includes a power save function 6. S/N=80dB typ. (Y/C mix:74dB typ.) 7. ESD strengh (aerial discharge) of ±15kV (IEC standard) 8. Includes mode select pins which correspond to various video signals Package SOP-16C Applications (1)DVD players (2)Digital STB (3)Other digital video equipment Video Signal Driver for DVD Players MM1566 MITSUMI Block diagram VCC1 1 16 VCC2 15 COUT 14 MODE 2 13 VOUT 12 VSAG 11 GND2 10 YOUT bias 150kΩ CIN 2 4dB LPF 75Ω Driver 2dB 6.75MHz MUTE1 3 CTRL sync tip clamp VIN 4 bias 150kΩ 4dB LPF 6.75MHz MODE 1 5 YIN 6 4dB 2dB + 75Ω Driver LPF 6.75MHz BIAS sync tip clamp bias 150kΩ 7 2dB 75Ω Driver bias GND1 8 9 YSAG Pin Assignment VCC1 1 16 VCC2 CIN 2 15 COUT MUTE1 3 14 MODE 2 VIN 4 13 VOUT MODE 1 5 12 VSAG YIN 6 11 GND2 BIAS 7 10 YOUT GND1 8 9 YSAG SOP-16C 1 2 3 4 5 6 7 8 VCC1 CIN MUTE1 VIN MODE 1 YIN BIAS GND1 9 10 11 12 13 14 15 16 YSAG YOUT GND2 VSAG VOUT MODE 2 COUT VCC2 Video Signal Driver for DVD Players MM1566 MITSUMI Pin Description Pin name Function 1 16 VCC1 VCC2 VCC 2 CIN Croma input Internal equivalent circuit diagram V CC 150k Pin No. 100µ 2 GND MUTE1 Mute select V CC 25µ 3 Using of MUTE and POWER-SAVING. 200 3 20k 20k 2.1V GND VIN YIN Video input V CC 150k The input can select Sync tip clamp or Bias 100µ 100µ 4 6 GND V CC 50µ Mode select 20k 5 14 1.4V GND 20k MODE1 MODE2 20k 5 14 100µ 4 6 Video Signal Driver for DVD Players MM1566 MITSUMI Pin Description Function 7 BIAS Bias Internal equivalent circuit diagram V CC 12.5k 7k 5.5k 7 GND 8 11 GND1 GND2 GND Signal output 10 13 V CC 2.2k 10 13 SAG correction 9 12 9 12 GND 15 COUT Croma output V CC 15 GND 100µ Pin name 100µ Pin No. Video Signal Driver for DVD Players MM1566 MITSUMI Absolute Maximam Ratings (Ta=25°C) Item Storage temparature Operating temparature Supply Voltage Power dissipation *1 Symbol TSTG TOPR VCC max.
