M420 Phase-Lock Clock

Summary: The M420 Phase-Lock Clock is a component designed for the data separator control of the RP15 Disk Pack Control. It features a phase error detector and a voltage-controlled oscillator (VCO), which are linked via a jumper between pins AV2 and AU2. The device produces a 5 MHz output with a 50 percent duty cycle at pin BK2, which can be divided by 1, 2, or 4 based on the input at pin BH2. The document also details the module's load specifications and its power requirements across -15V, +10V, and +5V rails.
