Note 3: This ICC-PWDN represents CLK, DATA, LE and CE being tied to either higher than 0.8 VCC or lower than 0.2 VCC.
Note 4: Phase noise is measured 1 kHz off from the carrier frequency. Comparison frequency is 200 kHz. OSCIN frequency is 13 MHz.
Note 5: Except fIN and OSCIN.
Note 6: Typical values are determined from measurements on the reference evaluation boards. A 3 dB (3 sigma) degradation is estimated from statistical distribution
in manufacturing. Units will NOT be tested in production.
Charge Pump Current Specification Definitions
DS101362-4
I1 = CP sink current at VCPo =VP − ∆V
I2 = CP sink current at VCPo =VP/2
I3 = CP sink current at VCPo = ∆V
I4 = CP source current at VCPo =VP − ∆V
I5 = CP source current at VCPo =VP/2
I6 = CP source current at VCPo = ∆V
∆V = Voltage offset from positive and negative rails. Dependent on VCO tuning range relative to VCC and ground. Typical values are between 0.5V and 1.0V.
1. ICPo vs VCPo = Charge Pump Output Current magnitude variation vs Voltage =
[12 * {|I1| − |I3|}] / [12 * {|I1| + |I3|}] * 100%
and
[12 * {|I4| − |I6|}] / [12 * {|I4| + |I6|}] * 100%
2. ICPo-sink vs ICPo-source = Charge Pump Output Current Sink vs Source Mismatch =
[|I2| − |I5|] / [12 * {|I2| + |I5|}] * 100%
3. ICPo vs TA = Charge Pump Output Current magnitude variation vs Temperature =
[|I2 @ temp| − |I2 @ 25˚C|] / |I2 @ 25˚C| * 100%
and
[|I5 @ temp| − |I5 @ 25˚C|] / |I5 @ 25˚C| * 100%
