Overview

STw80x9 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.

STw80x9 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, 2.8V/3.3V,

1.8V/2.8V and 1.2V/1.4V (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).
