GENERAL DESCRIPTION
The pll2128x is a Phase Locked Loop (PLL) frequency synthesizer. The PLL provide frequency multiplication
capabilities. Its output clock frequency FOUT is related to the input clock frequency FIN by the following
equation:
FOUT = (m
× FIN) / (p × 2
s
)
where FOUT is the output clock frequency. FIN is the input clock frequency. m, p and s are the values for
programmable dividers. pll2128x consists of a Phase Frequency Detector(PFD), a Charge Pump, an Off-chip
Loop Filter, a Voltage Controlled Oscillator (VCO), a 6-bit Pre-divider, an 8-bit Main-divider and 2-bit Post-scaler
as will be shown in functional block diagram.
FEATURES
— 0.13um CMOS device technology
— 1.5V single power supply
— Output frequency range: 20M ~ 100MHz
— Jitter:
±200ps at 100MHz
— Duty ratio: 40% to 60% (All tuned range)
— Power down mode
— Off-chip loop filter
— Frequency is changed by programmable divider
NOTES:
1.
Don't set the P or M as zero, that is 000000 / 00000000
2.
The proper range of P and M: 1
≤ P ≤ 62, 1 ≤ M ≤ 248
3.
The P and M must be selected considering stability of PLL and VCO output frequency range.
4.
Please consult with SEC application engineer to select the proper P, M and S values.
