Setup and Operating Instructions — SD130ASM Rev. G, Command Rev. 0.9
READ COMPLETELY BEFORE ATTEMPTING TO USE THIS EQUIPMENT.
SD130ASM Specifications —
DC input power: 7.5Vdc to 9.0Vdc ±5% @ 250mA, HD rate. Power supply ramp-up time <4ms. All device
supplies are regulated on-board.
Operating temperature range: 20°C, +30°C to –20°C (limited by crystal or oscillator module used)
RS-232 Command port: RS-232 standard levels for input and output. 9600 baud, 8 data bits, 1 stop bit, odd parity,
no flow control. Set the terminal or terminal emulator program to append a line feed after received carriage return
characters. Turn off local echo on terminal or terminal emulator program (The "Hyperterminal" program is
recommended).
TPG/BIST Crystal oscillator frequency: 27.000, 36.000, 54.000, 74.176 or 74.250MHz. Recommended operating
voltages are 3.3V and 5V, tolerance ±25ppm. The board is strapped for 5V operation and may be changed as
required. The optional oscillator XO1 is not supplied with the SD130ASM. A list of recommended manufacturers
and oscillators is given in the text.
Parallel Video Data and Other Inputs and Outputs: See LMH0030 datasheet for drive levels and other
specifications. The SD130ASM has provision for user installed connectors at all inputs.
SD130ASM Preliminary Setup —
Jumper Settings:
JP1 (Osc. Pwr.): This jumper is strapped for 5V operation. Cut the strap and solder a wire jumper from the center
via to the 3.3V via to change the voltage to 3.3V if required by the oscillator module being used. Note: Some
manufacturer's 5V oscillators will give satisfactory performance when operated at 3.3V. Consult the oscillator
manufacturer for details. Though the LMH0030 has 5V-tolerant inputs, use of input signal swings greater than 3.3V
pk-pk for Vclk may cause increased serial data jitter due to increased substrate currents caused by input signal
excursions above the 3.3V supply or undershoot below the circuit ground reference.
JP2 (DCE/DTE): This jumper is strapped for this assembly to operate as RS232 Data Communications Equipment
(DCE), the normal mode when communicating with a PC serial port. To set the port to Data Terminal Equipment
(DTE) communications mode for other types of computer equipment or specific applications, cut the straps and
solder wire jumpers across the vias in the same direction as the DTE legend, i.e. both jumpers align parallel with the
legend DCE (default) or with DTE (optional).
Test Jumpers: Not used on this assembly.
IMPORTANT ! BIST and TPG Oscillator Installation and Operation —
The assembly is supplied with the BIST/TPG pre-enabled by jumper strapping. The jumper will be found
connecting I/O 7 to +3.3V on the top side at connector position P2. To use the Built-In Self-Test (BIST) capability
of the LMH0030 to test the SD130ASM or to use the LMH0030 in its Test Pattern Generator (TPG) mode, a crystal
oscillator of the correct frequency for the video mode desired must be installed at XO1. Provision is made for two
common DIL case sizes, 14-pin and 8-pin. It is suggested that a suitable socket or socket pins be installed at XO1 so
that different oscillators may be installed as required for the available rates and formats. Use 27MHz for SD, 36MHz
for wide-raster SD and 74.25 or 74.18MHz for HD. Set the power supply jumper JP1 as described above.
To use the assembly for normal parallel to serial video data conversion, disable the BIST/TPG operation by cutting
the strap between I/O 7 and +3.3V.
