The
frequency synthesizer. The PLL provides frequency
multiplication capabilities. The output clock frequency
FOUT is related to the input clock frequency FIN by
the following equation:
pll2108x
is
a
Phase
Locked
Loop
(PLL)
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. pll2108x consists of a
Phase Frequency Detector(PFD), a Charge Pump, an
Off-chip Loop Filter, a Voltage Controlled Oscillator
(VCO), a 6bit Pre-divider, an 8bit Main-divider and
2bit Post-scaler as shown in functional block diagram.
0.13um CMOS device technology
1.2 Volt single power supply
Output frequency range: 50M ~ 300MHz
Jitter: ±150ps at 300MHz
Duty ratio: 40% to 60% (All tuned range)
Power down mode
Off-chip loop filter

NOTE
1.
Don't set the P or M value as zero, that is, seting the P=000000, M=00000000 can cause malfunction of the PLL.
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 contact SEC application engineer for proper selection of the P, M, S values of the PLL.
No responsibility is assumed by SEC for its use nor for any infringements of patents or other rights of third parties that
may result from its use. The contents of the datasheet is subject to change without any notice.
