SAA7104E; SAA7105E

Digital video encoder

Rev. 02 — 23 December 2005

Product data sheet

1. General description

The SAA7104E; SAA7105E is an advanced next-generation video encoder which

converts PC graphics data at maximum 1280 × 1024 resolution (optionally 1920 × 1080

interlaced) to PAL (50 Hz) or NTSC (60 Hz) video signals. A programmable scaler and

anti-ﬂicker ﬁlter (maximum 5 lines) ensures properly sized and ﬂicker-free TV display as

CVBS or S-video output.

Alternatively, the three Digital-to-Analog Converters (DACs) can output RGB signals

together with a TTL composite sync to feed SCART connectors.

When the scaler/interlacer is bypassed, a second VGA monitor can be connected to the

RGB outputs and separate H and V-syncs as well, thereby serving as an auxiliary monitor

at maximum 1280 × 1024 resolution/60 Hz (PIXCLK < 85 MHz). Alternatively this port

can provide Y, P_Band P_Rsignals for HDTV monitors.

The device includes a sync/clock generator and on-chip DACs.

All inputs intended to interface to the host graphics controller are designed for low-voltage

signals between down to 1.1 V and up to 3.6 V.

2. Features

■ Digital PAL/NTSC encoder with integrated high quality scaler and anti-ﬂicker ﬁlter for

TV output from a PC

■ Supports Intel Digital Video Out (DVO) low voltage interfacing to graphics controller

■ 27 MHz crystal-stable subcarrier generation

■ Maximum graphics pixel clock 85 MHz at double edged clocking, synthesized on-chip

or from external source

■ Programmable assignment of clock edge to bytes (in double edged mode)

■ Synthesizable pixel clock (PIXCLK) with minimized output jitter, can be used as

reference clock for the VGC, as well

■ PIXCLK output and bi-phase PIXCLK input (VGC clock loop-through possible)

■ Hot-plug detection through dedicated interrupt pin

■ Supported VGA resolutions for PAL or NTSC legacy video output up to 1280 × 1024

graphics data at 60 Hz or 50 Hz frame rate

■ Supported VGA resolutions for HDTV output up to 1920 × 1080 interlaced graphics

data at 60 Hz or 50 Hz frame rate

■ Three Digital-to-Analog Converters (DACs) at 27 MHz sample rate for CVBS (BLUE,

C_B), VBS (GREEN, CVBS) and C (RED, C_R) (signals in parenthesis are optional); all at

10-bit resolution

■ Non-Interlaced (NI) C_B-Y-C_Ror RGB input at maximum 4 : 4 : 4 sampling
