SAA4994H

2 GENERAL DESCRIPTION

The SAA4994H is a completely digital monolithic
integrated circuit which can be used for field and line rate
conversion of all global TV standards.

It features improved Natural Motion
It can be configured to emulate the SAA4990H as well as

the SAA4991WP. For demonstration purposes a split
screen mode to show the Dynamic Noise Reduction
(DNR) function and natural motion is available and a
colour vector overlay mode exists.

The SAA4994H supports a Boundary Scan Test (BST)
circuit in accordance with IEEE 1149.

Notes

1. Not used input pins should be connected to ground.

2. Because of the noisy characteristic of the output pad supply it is recommended not to connect the core supply and
the output pad supply directly at the device. The output pad supply should be buffered as close as possible to the
device.

7 FUNCTIONAL DESCRIPTION

The FAL (fal_top) module builds the functional top level of
the SAA4994H. It connects the luminance data path, the
chrominance data path and the luminance
(de)compression with SAA4994H inputs and outputs as
well as controlling logic. Outside of fal_top there are only
the pad cells, boundary scan test cells, the boundary scan
test controller, the clock tree, the test enable tree and the
input port registers.

Figure 4 shows a simplified block diagram of fal_top
module. It displays the flow of pixel data (solid lines) and
controls (broken lines) between the modules inside.

Basic functionality of the modules in fal_top module is as
follows:

• KER (kernel): Y (luminance) data path

• COL (colour): UV (chrominance) data path

• YDP (Y-DPCM): compression (and decompression) of

luminance output (and input) data by Differential Pulse
Code Modulation (DPCM)

• LSE (line sequencer): generate line frequent control
signals

• SNE (interface): Synchronous No parity Eight bit
Reception and Transmission (SNERT) interface to a
microcontroller.

The SNERT interface operates in a slave receive and
transmit mode for communication with a microcontroller,
which resides on peripheral circuits (e.g. SAA4978H)
together with a SNERT master. The SNERT interface
transforms serial data from the microprocessor (via the
SNERT bus) into parallel data to be written into the
SAA4994Hs write registers and parallel data from
SAA4994Hsreadregistersinto serial data to be sent to the
microcontroller. The SNERT bus consists of 3 signals:

1. SNCL: used as serial clock signal, generated by the

master

2. SNDA: used as bidirectional data line

3. SNRST: used as a reset signal, generated by the

microcontroller to indicate the start of a transmission.

SIGNAL LATENCY

RE_F 0
RE_C 62 cycles + REceShift
YC and UVC 63 cycles
RE_A 93 cycles + REaShift
YA and UVA 94 cycles
YF, YG, UVF

and UVG
WE_B 159 cycles + 4 input lines + WEbdShift
YB and UVB 159 cycles + 4 input lines

There is an algorithmic delay of 3 lines between input and
output data. Therefore, the main data output on the
F and G bus begins while the fourth input line is read.
Writing to the B and D bus starts one input line later. The
readandwriteenablesignalsRE_A,WE_BandRE_Ccan
be shifted by control registers REaShift, WEbdShift and
REceShift, which are implemented in the line sequencer.

The fal_top module itself reads the following control
register bits (addresses):

• NrofFMs (017H)

• MatrixOn (026H) and BusGControl (028H)

• MemComp and MemDecom (026H).

NrofFMs, MatrixOn and BusGControl are used to enable
the D and G output bus, respectively. MemComp and
MemDecom are connected to YDP to control luminance
data compression and decompression. These control
register signals are not displayed in Fig.4. Further
information on the control registers is given in Chapter 8.

147 cycles + 3 input lines

The processing of a video field begins on the rising edge
of the RE_F input signal. As indicated in Fig.4, the
SAA4994H receives its inputs andgenerates its outputs at
the following clock cycles after RE_F (see Table 1).
