CYW2338 - Dual Serial Input PLL

Description

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.

Features

  • Operating voltage 2.7V to 5.5V.
  • Operating frequency to 2.5 GHz on PLL1 and 1.1 GHz on PLL2 with prescaler ratios of 64/65 and 128/129.
  • Lock detect feature.
  • Power-down mode ICC < 1 µA typical at 3.0V.
  • Serial data input accepts data clock rates as low as 1 kHz.
  • Low power/voltage operation with low current standby www. DataSheet4U. com mode.
  • On-chip reference oscillator.
  • Available in a 20-pin TSSOP (Thin Shrink Small Outline Pac.
