2.0 General Programming Information
The LMX2531LQ1500E is programmed using 11 24-bit registers used to control the LMX2531LQ1500E operation. A 24-bit shift
register is used as a temporary register to indirectly program the on-chip registers. The shift register consists of a data field and
an address field. The last 4 register bits, CTRL[3:0] form the address field, which is used to decode the internal register address.
The remaining 20 bits form the data field DATA[19:0]. While LE is low, serial data is clocked into the shift register upon the rising
edge of clock (data is programmed MSB first). When LE goes high, data is transferred from the data field into the selected register
bank.
Although there are actually 14 registers in this part, only a portion of them should be programmed, since the state of the other
hidden registers (R13, R11, and R10) are set during the initialization sequence. Although it is possible to program these hidden
registers, as well as a lot of bits that are defined to either '1' or '0', the user should not experiment with these hidden registers and
bits, since doing will most likely degrade performance. Furthermore, this would be inconsistent to how these parts are tested.
