ML145146 Datasheet (LANSDALE Semiconductor) - 4-Bit Data Bus Input PLL Frequency Synthesizer

ML145146, 4-Bit Data Bus Input PLL Frequency Synthesizer

INPUT PINS D0 - D3 Data Inputs (Pins 2, 1, 20, 19) Information at these inputs is transferred to the internal latches when the ST input is in the high state.

D3 (Pin 19) is the most significant bit.

f in Frequency Input (Pin 3) Input to ÷N portion of synthesizer f in is typically derived from loop
