Product Summary
The U3666M-M is a Baseband Delay Line circuit. It is suitable for all chroma decoders with baseband color-difference outputs. The U3666M-M is suitable for PAL-, SECAM- and NTSC-signals as well. The U3666M-M contains two separate delay lines for processing (R–Y)-output and (B–Y)-output separately. The delay is performed by internally switched capacitors. On-chip post filtering avoids the need for external filter components. In the case of the U3666M-M, the post-filter is tuned to Bessel-characteristic.
Parametrics
U3666M-M absolute maximum ratings: (1)Supply voltage (pin 9): -0.5V to +7V; (2)Supply voltage (pin 1): -0.5V to +7V; (3)Voltage on pins 5, 11, 12, 14 and 16: -0.5V to VS V; (4)output current: 20mA; (5)Power Dissipation: 1.1W; (6)Storage temperature range: -25℃ to +150℃; (7)Electrostatic protection for input/output pins: 500V.
Features
U3666M-M features: (1)One line delay time, addition of delayed and non-delayed output signals; (2)Adjustment-free application, VCO without external components; (3)Handles negative or positive color-difference input signals; (4)Improved latch-up stability; (5)Improved power supply rejection ratio (PSRR); (6)No crosstalk between SECAM color carriers (diaphoty); (7)Comb-filtering functions for NTSC color difference signals; (8)Correction of phase errors in the PAL system.
