(ADV7380)EX_LF resistor and capacitor value

Question

Hi! 
 Our customer is asking about EXT_LF specification. 
 There is no specification at the datasheet. 
 But I asked about this at past. 
 (ADV7390)EXT_LF resister 
 But I want to make sure. 
 Q1) 
 What is the specification for 12nF and 150nF and 170Ω? 
 12nF ± ??% 
 150nF ± ??% 
 170Ω ± ??% 
 12nF ± 10% 
 150nF ± 10% 
 170Ω ± 5% 
 are OK? 
 
 Q2) 
 If our customer change the resistor and capacitor , how can they check that the value is correct? 
 Which kind of test should they do? 
 Also our customer want to know this as soon as possible so if you can help about this , it would help our customer. 
 Best regards 
 Kawa

170 5% is fine 
 2) The device is only specific with these values as they are defined. Changing the the values will change the PLL loop performance. We will only standby data sheet specs with these parts. If the customer changes the values it might work but they are on their own. Tolerance changes were part of the initial design so as long as the tolerance is 10% or better, it's OK. 
 2) If they are just changing vendors then matching spec'd part from new vendor is good.
