DTMB (S11<-8)
Application
DVBT/T2 ( with S1 filter for EN55020)
ATV only, ATSC ,ISDBT (S11>-8)
CT4
的选取：
1.
内置隔离器时，
CT4=0R
2.
不带内置隔离时，
CT4=470PF
MSTAR 方案， AGC 采用电流型输出， RT3 的不易过大。
其他方案，可采用参考设计要求的 10K.
靠近 silicon tuner 摆放
供电范围： 3.13~3.47V
实测电流：
240mA

(1) +VDD3V input voltage tolerance must be under +-5%
(2) +VDD3V input ripple must be under 30mVpp
(3) Using LDO for +VDD3V is recommended
- filter noise from demod side
kick back filter 改善 ATV 水波纹！

Recommend to reserve R106, R110, R109
to filter noise from demod side.

- R103 and R106 are related to Demod side's
IFAGC design. Sometime need to fine tune
for different Demod.
- Following IFAGC TBD table is common
suggestion.
