Y/C one-chip processor (VHS standard)TDA9715H/A
FEATURES
• Luminance Noise Reduction (YNR)
• Chrominance Noise Reduction (CNR)
• Saturation dependent writing current control (CACC)
GENERAL DESCRIPTION
The TDA9715H/A is an integrated circuit for chrominance
and luminance processing (record and playback) in VHS
tape recorders for the TV standard PAL, NTSC,
SECAM/ME (4.43 MHz chrominance systems).
L
The CVBS signal appears at the output pin 57 and at the
internal Y Low-Pass Filter (YLPF) via pin 60 and
Automatic Gain Control (AGC) stage. Exempt from
chrominance, the luminance signal is fed first to the sync
separator stage to obtain the separated sync pulse at
pin 64 and secondly via Non-Linear Emphasis (NLE), main
emphasis, white-dark clip and FM modulator to the FM
output pin 6.
HROMINANCE
C
Exempt from the luminance signal in the internal 4.43 MHz
band-pass filter and controlled by the Automatic
Chrominance Control (ACC) stage the chrominance signal
is mixed in the band mixer with a 4-phase shifted 5.06 MHz
signal, produced by the internal adjustment-free oscillator.
The formed N × fH signal is fed via an internal low-pass
Playback/Video-to-Video (PB/VV) mode
LUMINANCE
The FM signal is fed to the FM demodulator stage and the
internal sub low-pass filter (DLPF) via input pin 8 and the
double limiter. After passing main de-emphasis,
Non-Linear De-emphasis (NLDE) and the luminance
Noise Reduction (YNR) the signal is fed first to the sync
separator stage and then (via picture control stage) mixed
with the chrominance signal. This CVBS signal is output at
pin 57.
HROMINANCE
C
The internal N × fH band-pass filter (BPF 627 kHz) and the
ACC stage the signal is mixed in the band mixer with a
4-phase shifted 5.06 MHz signal, produced by the internal
adjustment-free oscillator via input pin 41. The formed
fSC-chrominance signal is fed via internal BPF 4.43 MHz,
external comb filter and internal Chrominance Noise
Reduction (CNR) to the internal Y/C mixer.
filter and CACC to the output at pin 34.
