• Manufacturer Part Number: zl10038
• Description: Advanced Modulation Dvb-s2 Compliant Satellite Tuner With Bypass
• Manufacturer: ETC-unknow

3.4.17
Bits LS2:0 (bit-2 to bit-0 respectively in byte-10) set the LO sample rate according to the following table:
3.4.18
Byte-11 allows the user to change the lock and unlock window voltages that the tuning controller uses in
comparison with the Vvar input. Setting the WS bit to ‘0’ allows the lock levels to be altered, or if set to ‘1’, the
unlock levels are written. The WH2:0 bits set the upper levels and the WL2:0 bits set the lower levels in each case.
Please see “Power-On Software Initialization” (sect. 4.1) on page 30 for recommended values.
