SAA7127H
TYPE NUMBER
Monolithic CMOS 3.3 V device, 5 V I
Digital PAL/NTSC encoder
System pixel frequency 13.5 MHz
54 MHz double-speed multiplexed D1 interface capable
of splitting data into two separate channels (encoded
and baseband)
Four Digital-to-Analog Converters (DACs) for CVBS
(CSYNC, VBS), RED (Cr, C), GREEN (Y, VBS) and
BLUE (Cb, CVBS) two times oversampled (signals in
parenthesis are optionally). RED (Cr), GREEN (Y) and
BLUE (Cb) signal outputs with 9-bit resolution, whereas
all other signal outputs have 10-bit resolution; CSYNC is
an advanced composite sync on the CVBS output for
RGB display centring.

DESCRIPTION
GENERAL DESCRIPTION
The SAA7126H; SAA7127H encodes digital Cb-Y-Cr
video data to an NTSC or PAL CVBS or S-video signal.
Simultaneously, RGB or bypassed but interpolated
Cb-Y-Cr signals are available via three additional
Digital-to-Analog Converters (DACs). The circuit at a
54 MHz multiplexed digital D1 input port accepts two CCIR
compatible Cb-Y-Cr data streams with 720 active pixels
per line in 4 : 2 : 2 multiplexed formats, for example MPEG
decoded data with overlay and MPEG decoded data
without overlay, whereas one data stream is latched at the
rising, the other one at the falling clock edge.
It includes a sync/clock generator and on-chip DACs.
PACKAGE
Macrovision Pay-per-View copy protection system
rev. 7.01 and rev. 6.1 as option; ‘handsfree’ Macrovision
pulse support through on-chip timer for pulse amplitude
modulation; this applies to SAA7126H only. The device
is protected by USA patent numbers 4631603, 4577216
and 4819098 and other intellectual property rights.
Use of the Macrovision anti-copy process in the device
is licensed for non-commercial home use only. Reverse
engineering or disassembly is prohibited. Please
contact your nearest Philips Semiconductors sales
office for more information.
Controlled rise/fall times of output syncs and blanking
On-chip crystal oscillator (3rd-harmonic or fundamental
crystal)
Down mode (low output voltage) or power-save mode of
DACs
