11 / 22 page No. 6113-11/22 LC72122V Continued from preceding page. DO Output Data (Serial Data Output) Structure 3. OUT mode DO Output Data No. Control block/data Description Related data IF counter control data • IFIN pin input sensitivity control data. This data should be set to 1 in normal operation. (11) IFS Setting this data to 0 switches the LC72122V to a reduced input sensitivity mode in which the sensitivity is reduced by 10 to 30 mVrms. Sub-charge pump control • This data controls the sub-charge pump (PDS) which is provided for fast locking. (12) data By setting SUBC to 1, applications can set the sub-charge pump circuit to the operating UL0, UL1 SUBC state and increase the speed of frequency looking. IC test data • IC test data TEST 0 to TEST2 TEST0 (13) TEST1 All three bits must be set to 0. TEST2 All the test data is set to 0 at a power-on reset.** (14) DNC Data is set to 0 No. Control block/data Description Related data I/O port data • Data latched from the states of the I/O ports, pins IO1 and IO2. I2, I1 • This data reflects the pin states, regardless of whether they are in input or output mode. • The data is latched when OUT mode is selected. I1 ← IO1 pin state High: 1 I2 ← IO2 pin state Low: 0 PLL unlock data • Data latched from the state of the unlock detection circuit UL UL ← 0: Unlocked UL ← 1: Locked or in detection stopped mode IF counter binary data • Data latched from the state of the IF counter, which is a 20-bit binary counter. C19 to C0 C19 ← Binary counter MSB C0 ← Binary counter LSB (1) (2) (3) IOC1, IOC2 UL0, UL1 CTE, GT0, GT1 * Note: * Data with a value of “0” **Note : Although the IC is initialized after power is first applied by the power on reset circuit, applications must also send a full set of data over the CCB bus immediately after power is first applied to assure safe and stable operation. |
