Single Tone Generation
for RF Test
Modulated Carrier
Generation for RF Test
TST3 (TEST CONFIGURATION3 REGISTER, 0x2263) R/W.
This register is used to support the generation of a random symbol for the modulation in a test
mode. The Random Number Generator (RNG) generates the random number by CRC-16.
TST3 register stores the seed for RNG circuit. Any number except ‘0’ can be used as the seed
for RNG circuit.
TST13 (TEST CONFIGURATION13 REGISTER, 0x226D) R/W.
This register sets the length of transmitting packet in a test mode. The length of packet can be
set from 1 byte to 127 byte and the duration of each packet is from 256µs to 4,256µs.
TST14 (TEST CONFIGURATION14 REGISTER, 0x226E) R/W.
This register sets the frequency of a single-tone in a test mode for transmitting single-tone.
TST14 register can set from a 1/4 frequency of DAC operating clock to a 1/256 frequency of
DAC operating clock. This single-tone signal can be used to test RF block characteristics.
Cosine and sine signal can be selectively assigned to I-phase or Q-phase of RF block.
The frequency of single-tone is defined by Equation 5.
TST1 (TEST CONFIGURATION1 REGISTER, 0x2261)
This register defines the fixed symbol to be modulated for generating a test packet. TST1 register sets
two fixed symbols.
TST2 (TEST CONFIGURATION2 REGISTER, 0x2262)
This register sets the inter-packet time interval when the test mode transmits the modulated packet of a
random data. The inter-packet time interval is needed for setting-up EVM measurement.

Test Symbol, Low Nibble. Sets the symbol to be transmitted first in
fixed symbols.
Test Symbol, High Nibble. Sets the symbol to be transmitted later in
fixed symbols.
Inter-frame Space. Sets the number of the symbols corresponding to
the inter-packet time interval in the IFS field. The duration of 1 symbol is
16µs. Therefore, if IFS is set to ‘N’, inter-packet time interval is set to
(16*N) µs. Note: The defined value of the IFS field is valid only when the
TSTMD field is set to ‘23’.
