(Continued)
• Direct power saving function : Power supply current in power saving mode
Typ. 0.1 µA (VCC = Vp = 3.0 V, Ta = +25 °C) , Max. 10 µA (VCC = Vp = 3.0 V)
• Fractional function : modulo 13 fixed (implemented in RF-PLL)
• Dual modulus prescaler : 2000 MHz prescaler (16/17 fixed) /600 MHz prescaler (8/9 or 16/17)
• Serial input programmable reference divider : RF : 7 bit (3 to 127) /IF : 14 bit (3 to 16383)
• Serial input programmable divider consisting of :
RF section - Binary 4-bit swallow counter : 0 to 15
- Binary 10-bit programmable counter : 18 to 1,023
- Binary 4-bit fractional counter numerator : 0 to 15
IF section - Binary 4-bit swallow counter : 0 to 15
- Binary 11-bit programmable counter : 3 to 2,047
• On-chip phase comparator for fast lock and low noise
• Operating temperature : Ta = −40 °C to +85 °C
• Small package Bump Chip Carrier.0 (3.4 mm × 3.6 mm × 0.6 mm)
