Description
TMC22061P7C encoder demonstration board converts 8-bit parallel digital component video, (CCIR Rec. SMPTE 125, a.k.a. "601") into analog composite video using TMC22091 digital video encoder. board supports multiple standards, operating PAL, PAL-M, NTSC, NTSC-EIA (zero setup) television formats. crystal oscillator provided cases where CCIR-601 source available. When operated from on-board oscillator, only internally generated color bars modulated ramp produced. TMC22061 designed demonstrate performance TMC22x91 family Digital Video Encoders, while providing convenient testbed developing specific programming encoder evaluating resulting waveforms. also offers example design practices that result high-quality video performance. board supports multiple standards, operating PAL, PAL-M, NTSC, NTSC-EIA (zero setup) television formats. data must provided with proper frame rate, supported 50Hz format produced with supplied programs.

PRODUCT SPECIFICATION
board accepts 8-bit parallel digital component video, (CCIR Rec. SMPTE 125, a.k.a. "601") standard connector differential format, translates data format, strips Timing Reference Signal from datastream generate Sync, passes digital video stream Encoder 16-bit 13.5 format. simple EPROM-based programmer provided, which downloads selected configuration (one Encoder when reset button pressed. This EPROM holds both control register data Color-Look-Up-Table (CLUT) patterns blocks. Sixteen pages selected rotary switch, additional switches provided selecting among four banks. crystal oscillator provided cases where CCIR-601 source available. When operated from on-board oscillator, only internally generated color bars modulated ramp produced. board operates from standard supplies. When used stand-alone mode, only required.
Software Reset
software reset occurs whenever pushbutton switch, depressed. software reset latched through ensure known relationship between internal pixel clock TMC22091 externally generated LDV, PDC, VHSYNC\, VVSYNC\ signals. When depressed internal state machines TMC22091 reset outputs disabled. When released program counter started beginning next vertical blanking period. Software Reset required after power-up after each functional change.
Programming TMC22091
12-bit counter (U6, used produce addresses used programming TMC22091. produces required R/W\, A1:0, signals, while contains different pages setup data NTSC another pages (selected switch S2). Switch selects between different flavors NTSC operation. ensure that outputs programmable logic correctly timed transitions microprocessors data bus, they addressed four times rate that addressed. pages setup data selected rotary switch shown Table
CCIR-601 Interface
CCIR-601 data stream terminated into differential ECL-to-TTL converters. translated data latched through rate then passed demultiplexer. Here, luminance chrominance data words separated into data streams termed respectively. This data goes directly into TMC22091, which separates data stream into color difference signals interpolates them same sample rate data. This interpolation improves horizontal color definition. decoder extracts field (F), vertical blanking (V), horizontal blanking information from data stream timing signal generation board. decoder also produces pixel counter reset signal latching data into TMC22091.

Horizontal Vertical Timing
pixel counter (U4, decoded produce VHSYNC\ signals required TMC22091 horizontal synchronization. line rate clock, H/2_CLK, used VVSYNC\ generation, also produced along with P_CLOCK DATA_EN. P_CLOCK used clock program counters DATA_EN signal used demultiplexing circuit. 4-bit counter embedded started whenever goes HIGH, which occurs beginning each vertical blanking interval. This counter clocked H/2_CLK, which enables VVSYNC\ pulse produced same time first vertical sync pulse each field. output signal ensures that software reset signal, RES_OUT, goes HIGH half-line periods before program counter starts.

Output Reconstruction Filters
oversampling internal digital data before output converters TMC22091 only reduces Sin(x)/x high-frequency roll-off eliminates complicated reconstruction filters. This particularly important frequency response digital filters dependent upon sample rate, while frequency aliased subcarrier component fixed. TMC22091 encoder designed drive line, terminated both source load (that 37.5 load.) filters internally source terminated. Optional load terminations provided board. these required, simply remove appropriate links behind connectors (E4, E6).

Operation Without CCIR-601 Source
Only rotary switch positions useful without CCIR-601 digital video source available. These switch positions produce color bars modulated ramp. These test patterns inserted into pixel data path after CLUTs format demonstrate circuitry TMC22091. provide PXCK absence CCIR-601 source, switch INTernal.

Power Supply Requirements
TMC22061P7C board requires 1.25 Amps from Volt power supply 0.25 Amps from Volt power supply. Volt power supply powers logic devices which have relatively good noise immunity. Volt power supply only drives logic devices also provides power TMC22091. Therefore, recommended that bench power supply used with cable lengths kept minimum. When operating stand-alone mode, only Volt supply required.
