Description
STw8009/STw8019 is aimed at mobile video
Digital ENCoder (DENC). This device converts
digital video signals into high quality analog signal
compliant with TV standards, it is able to encode
interlaced (in all standards) and non-interlaced (in
PAL and NTSC).

TFBGA 4 mm x 4 mm x 1.2 mm
VFBGA 3 mm x 3 mm x 1.0 mm
Featuring ultra low power consumption, it suits
perfectly mobile appliances that interface
occasionally with TV sets or VCRs. It is also the
ideal companion for digital application processors
such as ST’s Nomadik family.
To minimize PCB space usage,
STw8009/STw8019 features a high level of
integration. STw8009/STw8019 drives directly the
video input, CVBS of a TV set or the Y/C video
input of a VCR through optional ESD protection
devices.
The 27 MHz clock and the device power
management are controlled through the digital
processor interface [PORn, Suspend and 2-wire
I2C compatible serial MPU]. This digital processor
interface also controls the STw8009/STw8019
operating modes (off, sleep, standby and active).

Functional description
4.5 Sub-carrier generation
A Direct Digital Frequency Synthesizer (DDFS) generates the required color sub-carrier
frequency using a 24-bit phase accumulator. Sub-carrier frequency is programmable with a
1.6 Hz step.

Luminance encoding
The luminance that is added to the chrominance to create the composite CVBS signal can
be trap-filtered at 3.58 MHz (NTSC) or 4.43 MHz (PAL). This supports application oriented
towards low-end TV sets which are subject to cross-color.
A 7.5 IRE pedestal can be programmed if needed with all standards. This allows in
particular to encode Argentinian and non-Argentinian PAL-N, or Japanese NTSC.
A programmable delay can be inserted on the luminance path to offset any chroma/luma
delay introduced by off-chip filtering.
STw8009/STw8019 output signals are IF modulated in NTSC M standard so that a sound
notch filter is required. The notch filter which is on the Luma path is defined by a set of
coefficients and is implemented in the STw8009/STw8019 as default values. The set is also
programmable.
