●IF frequency setting

IF frequency is 200kHz. IF frequency corresponds to each oepration frquency must be selected as below.

Operating Frequency

(ML7344E)

315 to 450MHz

(ML7344J)

470 t0 510MHz

(ML7344C)

PLL division setting

[PLL_DIV_SET:B1 0x1A]

0x10

0x00

IF frequency setting

[IF_FREQ_H/L:B0 0x54-55]

0x1F81

0x0FC0

PLL reference frequency (=master clock frequency: FMCK1)

[Example] ML7344C/J

IF_FREQ= {(0. 2MHz / 2) / 26MHz} * 220 (Integer part) = 4032 (0x0FC0)

[IF_FREQ_H: B0 0x54] = 0x0F

[IF_FREQ_L: B0 0x55] = 0xC0

[Example] ML7344E

IF_FREQ= {(0. 2MHz / 2) / (26/2)MHz} * 220 (Integer part) = 8065 (0x1F81)

[IF_FREQ_H: B0 0x54] = 0x1F

[IF_FREQ_L: B0 0x55] = 0x81
