Functional Description
Video Input Formats
The TW280X supports all NTSC/PAL standard formats and has built-in automatic standard
detection circuit. The following Table 1 shows the identified standards. Automatic standard
detection can be overridden by writing the value into the IFMTMAN and IFORMAT register
(0x01, 0x41, 0x81, 0xC1). Even in no-video status, the device can be forced to free-run in a
particular video standard mode for fast locking by programming IFORMAT register.

Analog-to-Digital Converter
The TW280X contains four 10-bit Analog to Digital converters that digitizes the analog video
inputs. As the inputs are digitized at greater than two times that of the Nyquist sampling rate,
only simple external anti-aliasing LPF are needed to prevent out-of-band frequencies. Each
ADC has two analog switches that are controlled by ANA_SW (0x22, 0x62, 0xA2, 0xE2)
registers. The A/D converters can also be put into power-down mode by the ADC_PWDN
(0x78) registers.
