• Description: Digital multistandard colour decoder with SCART interface DMSD2-SCART
• Manufacturer: Philips Semiconductors

Philips Semiconductors
Notes
1. Data output signals are Y7 to Y0 and UV7 to UV0. All other are control signals.
2. Levels are measured with load circuit. YUV-bus, HREF and VS outputs with 1.2 k in parallel to 50 pF at 3 V
3. Recommended crystal: Philips 4322 143 05291.
