TC90A53N/F
TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
TC90A53N,TC90A53F
3-LINE DIGITAL Y / C SEPARATOR IC
TC90A53N / F is a 3-line digital Y / C separator IC which separates
luminance signal Y and chroma signal C from composite video signals.
Toshiba’s logical comb filter realizes good Y / C separation at low cost.

· Dynamic comb filter
· Vertical edge enhancement circuit
· PLL 4 × multiplier circuit
· Internal 8-bit 4 fsc AD converter
· Internal 8-bit 4 fsc DA converter (2 ch)
· 1-line color dot interference reducer circuit
· Sync tip clamp circuit
· Internal 2H-line memory
· Color killer mode (Y / C separation off)
· Chroma signal C output wide band mode
· Package : SDIP 28-pin and SOP 28-pin
· 5 V single power supply
