General Description
The PMB 2306, PMB 2307 PLL are high speed CMOS ICs are especially designed for use in battery-powered radio equipment and mobile telephones. The intended application will be in GSM, PCN, DECT and other digital mobile systems. The wide range of dividing ratios also allows application in analog systems.

FEATUREs
• Low operating current consumption
• Low operating voltage
  PMB 2306: 3 V to 5.5 V
  PMB 2307: 2.7 V to 5.5 V
• High input sensitivity, high input frequencies (220 MHz)
• Extremely fast phase detector without dead zone
• Linearization of the phase detector output by current sources
• Synchronous programming of the counters (N-, N/A-, R-counters) and system parameters
• Fast modulus switchover for 65-MHz operation
• Switchable modulus trigger edge
• Large dividing ratios for small channel spacing
  – A-scaler 0 to  127
  – N-scaler 3 to 16380
  – R-scaler 3 to 65535
• Serial control (3-wire bus: data, clock, enable) for fast programming (fmax ∼5 MHz)
• Switchable polarity and rate of trimming rise of the phase detector
• 2 multifunction outputs
• Digital phase detector output signals (e.g. for external charge pump)
• frn, fynoutputs of the R- and N-scalers
• Port 1 output (e.g. for standby of the prescaler)
• External current setting for PD output
• Lock detect output with gated antibacklash pulse (quasi digital lock detect)
