Overview
STw8009/STw8019
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).
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, the device features a high level of integration. The 35 mA
high performance DAC allows direct drive of 37.5 Ω load.
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. It is powered by three voltage supplies,
2.8/3.3 V, 1.8 V and 1.2 V (VccA, VI/O, Vdd).
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 operating modes (off, sleep, standby and active).
