TENTATIVE DESCRIPTION OF FUNCTION AND OPERATION (1) Serial data control
TB31356AFL
TB31356AFL operates according to serial data program. Serial data is input from the clock (CLK), data (DATA), and strobe (STB) pin. (2) l Entry of serial data At the rising edge of each clock pulse, data is sent to the internal shift register from the LSB sequentially. When all the data is sent, set the strobe pin to high. At this rising edge, data is stored in latches depending on the control contents. At the same time as data is stored, control starts. The CLK, DATA, and STB pin contain the schmitt trigger circuit to prevent the data errors by noise, etc. At power on, send the option control data before any other divider data.

TENTATIVE l Lock detection
TB31356AFL
A signal indicating whether the PLL has phase-locked to the desired frequency is presented to the LD pin. The PLL to be detected in this way can be selected by setting two bits, LD1 and LD2, as shown in the table below. LD1 0 0 1 1 LD2 0 1 0 1 Detected PLL Not detected (fixed low) PLL2 PLL1 Only when both PLL1 and PLL2 are
detected Locked in phase = open, Unlocked = low, Power-down mode = open
l
Power-down mode
The PLL1, PLL2, and crystal oscillator circuit can be switched between operating and power-down modes by using three bits--SB1, SB2, and SBX. The table below shows how operation is controlled by using these bits and external battery save pins.

Notes3 : Switching between operating and battery saving (power down) mode by using external pin (BS-PLL1,BS-PLL2) is controlled real-time. Notes4 : Immediately after power on, need a initial setting by serial data before operation state "ON".
