2. WO: White Clip Off Mode

TA1326FNG

1: Disables white clip function, e.g. when modulation characteristics for near-100% modulation are being

checked.

0: Enables white clip function (default).

3. PSA: Power Save Mode

1: Disables power saving (default).

0: Enables power saving. The device waits for data from the bus with all blocks other than the bus decoder

turned off.

In Power Save Mode, the device retains all data values as long as VCC is applied. Turning VCC off and on

again will trigger a power-on reset, causing all data values to be initialized.

6. N9~N0 (NA): Programmable divider data

The RF VCO oscillation frequency is calculated using the following formula.

fVCO = 62.5 kHz × 16 × N + 250 kHz

N = 512 × N9 + 256 × N8 + 128 × N7 + 64 × N6 + 32 × N5 + 16 × N4 + 8 × N3 + 4 × N2 + 2 × N1 + N0

The frequency varies in steps of 1 MHz. The +250-kHz term in the formula is hard-wired into the IC.

The divider N is obtained by subtracting 250 kHz from the frequency setting.
