PMB2306T SIEMENS [Siemens Semiconductor Group], PMB2306T Datasheet - Page 4

• Manufacturer Part Number: PMB2306T
• Description: PLL-Frequency Synthesizer PMB2306R/PMB2306T Version 2.2
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

• Low operating current consumption
• High input sensitivity, high input frequencies
• Extremely fast phase detector without dead zone
• Linearization of the phase detector output by current
• Synchronous programming of the counters
• Fast modulus switchover for 65-MHz operation
• Switchable modulus trigger edge
• Large dividing ratios for small channel spacing
Semiconductor Group
• Serial control (3-wire bus: data, clock, enable) for fast programming (
• Switchable polarity and phase detector current programmable
• 2 Multifunction outputs
• Digital phase detector output signals (e.g. for external charge pump)
•
• Port 1 output (e.g. for standby of the prescaler)
• External current setting for PD output
• Lock detect output with gated anti-backlash pulse (quasi digital lock detect)
The PMB 2306T PLL is a high speed CMOS IC, especially designed for use in battery powered
radio equipment and mobile telephones. The primary applications will be in digital systems e.g.
GSM, PCN, ADC, JDC and DECT systems. The wide range of dividing ratios also allows application
in modern analog systems
