• 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 3 to 16 programmable (implemented in RF-PLL)
• Dual modulus prescaler : 2500* MHz prescaler (16/17 or 32/33) /600 MHz prescaler (8/9 or 16/17)
• Serial input 14-bit programmable reference divider : R = (RF section 8 bit) 3 to 255, (IF section 14 bit) 3 to
16, 383
• Serial input programmable divider consisting of :
RF section - Binary 5-bit swallow counter : 0 to 31
- 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)
* : In case of fmax = 2500 MHz, the following conditions must be fulfilled. Except for it, fmax is up to 2000 MHz.
Prescaler ratio = 32 (N > P) at all divide ratio of used operating frequency.
Refer to a calculation formula of divide ratio. fVCORF = (P×N+A+F/Q) ×fOSC/R
