VU+ SE V1,V2 Higher symbol Rate Transponders Problem

[mianabid]

Vu+ is such a pathetic company that I'm sending them emails since last one year but no solution from them, not going to buy or sell their any product in future

Issue is still not rectified. Some transponder with 44995 symbol rate is tuned but some don't. (8psk)

Data sheet of AVL 6211 confirm it supports symbol rates up to 45000




Description
DVB-S2/DVB-S Channel Receiver Data Sheet
The AVL6211 is an enhanced version of the AVL2108 device. The AVL6211 is a highly integrated DVB-S2 and DVB-S channel receiver IC. It converts a baseband analog IQ signal from a satellite tuner and performs
Applications
• Digital satellite receiver for standard and high definition TV
• High speed satellite data receiver
Features
Confidential for Honestar a set of sophisticated demodulating and
decoding operations to output an MPEG video/audio stream. The AVL6211 provides simple and flexible control via a standard two-wire bus. A simplified block diagram of the device is shown in Figure 1-1.
The AVL6211 includes dual, differential, high performance, analog to digital converters (ADC) with a built-in compensation circuit for DC offset and IQ imbalance. An RF AGC output is provided for simple gain control of the satellite tuner via an RC network.
After passing a timing recovery loop and frequency recovery loop, the signal samples are further processed by an equalizer to output decision bits to an FEC decoder. The decoded bits are finally packetized in the MPEG interface block.
The configuration of the AVL6211 is easily performed through a set of registers via a standard two-wire bus. To simplify the interface to the host system, this same two- wire bus is used to communicate with the separate tuner two-wire bus and the DiSEqC™ interface to the LNB.
The AVL6211 can achieve fast acquisition at frequency offsets up to 5 MHz and maintains synchronization under the most severe front- end phase noise.
**Refer to Table 7-1
• High performance QPSK/8PSK satellite TV receiver
• 64 pin LQFP in 7x7 mm package
• Low 250 - 270 mW power (clear sky)**
• Low 330 - 460 mW power (threshold)**
• DVB-S2:

• Carrier frequency acquisition range: ±5MHz for symbol rates above 3 Msps and ±3MHz for the remaining symbol rates
• Signal quality and BER/PER monitors
• Equalizer compensates for channel impairment
• Standard two-wire serial bus with two selectable addresses for easy chip configuration
• Multi-purpose modulator for DiSEqC™ applications
• Standard MPEG-2 transport output parallel and serial interfaces

And your point is what? Do you think it should work perfect up to 44999 and then stop working at 45000?

Some transponders of St 2 88e is working .for example 11483v 44995 dvb-s2 8psk .so it should be able to handle those high symbol rates.but not tuned 11483H 44995.
I'm not sure about it stops working immediately at 45000.
