KKA4661
KKA4661 is BASEBAND DELAY LINE manufactured by Kodenshi AUK Group.
.. TECHNICAL DATA BASEBAND DELAY LINE GENERAL DESCRIPTION The KKA4661 is an integrated baseband delay line circuit with one line delay. It is suitable for decoders with colour-difference signal outputs ± (R-Y) and ± (B-Y). Device is functionally identical to the TDA4661 Philips. Features - Two b filters, using the switched-capacitor technique, for one line delay time (64 µS) - 3 MHz internal clock signal derived from a 6 MHz CCO, line-locked by the sandcastle pulse (64 µS line) - b filtering functions for NTSC colour-difference signals to suppress cross-colour - Clamping of AC-coupled input signals ± (R-Y) and ± (B-Y) QUICK REFERENCE DATA Parameter Analogy supply current, m A Digital supply current, m A Input fixing voltage (on pins 14 and 16), V Output voltage (on pins 11 and 12), V Output signal (peak-to peak value) ± (R-Y) on pin 11 ± (B-Y) on pin 12 Ratio of output amplitudes at equal input signals (U14=U16=1.33V), d B Ratio of output signals on pins 11 and 12 for adjacent time samples at constant input signals (U14=U16=1.33V), d B Gain for PAL and NTSC Gain for SECAM (ratio UO/UI), d B Delay of delayed signals, µS Delay of non-delayed signals, n S Transient time of delayed signal on pins 11 respectively 12, n S Transient time of non-delayed signal on pins 11 respectively 12, n S Noise voltage (RMS value; pins 11 and 12), m V Weighted signal-to-noise ratio, d B Symbol Ip1 Ip2 U14,16 U11,12 U011 U012 U11/U12 Un/Un+1 Min. 1.3 2.5 -0.4 -0.1 Type UVCC=5.0 V Type 1.05 1.33 Max 6.0 1.0 1.7 3.3 0.4 0.1 Gv td tdn ttr ttrn Un S/N(w) 5.3 -0.6 63.94 40 - 350 320 54 6.3 0.4 64.06 80 1.2 - 1 ..
