CYW2338 Datasheet (Cypress Semiconductor)

CYW2338, Dual Serial Input PLL

CYW2338 Power Supply Connection for PLL1 and PLL2: When power is removed from both the VCC1 and VCC2 pins, all latched data is lost.

PLL1 Charge Pump Rail Voltage: This voltage accommodates VCO circuits with tuning voltages higher than the VCC of PLL1.

PLL1 Charge Pump Output: The phase detector g
