BGA3031
DOCSIS 3.0 plus upstream amplifier
Rev. 3 — 20 November 2014
Product data sheet
1. General description
The BGA3031 is an upstream amplifier meeting the Data Over Cable Service Interface
Specifications (DOCSIS 3.0). It is designed for cable modem, CATV set top box and VoIP
modem applications. The device operates from 5 MHz to 85 MHz. The BGA3031 provides
58 dB gain control range in 1 dB increments with high incremental accuracy. Its maximum
gain setting delivers 34 dB voltage gain and a superior linear performance.
It supports high output power levels, exceeding the DOCSIS 3.0 power levels while
minimizing distortion and output noise levels. The BGA3031 is capable of transmitting
1 to 8 64-QAM and 1 to 8 QPSK modulated carriers while meeting the DOCSIS 3.0 ACLR
specification under DOCSIS 3.0 + 4 dB conditions.
The BGA3031 operates at 5 V supply. The gain is controlled via a 3-wire serial interface.
The current consumption can be reduced in 4 steps via the serial interface. This enables
the user to optimize between DC power efficiency and linearity. In addition the current is
automatically reduced at lower gain settings while preserving the linearity performance. In
disable mode the device draws typical 6 mA while it still can be programmed to new gain
and current settings.
The BGA3031 is housed in 20 pins 5 mm 5 mm leadless HVQFN package.

8.1 Logic programming
The programming word is set through a shift register via the data, clock and chip select
lines. The data is entered in order with the Most Significant Bit (MSB) first and the Least
Significant Bit (LSB) last. The chip select line must be LOW for the duration of the data
entry, then set HIGH to latch the shift register. The rising edge of the clock pulse shifts
each data value into the register.

8.2 Register settings
8.2.1 Register address
Only addresses 0000 and 0001 are used. Using any other addresses will not affect the
VGA.
8.2.2 Gain/attenuator setting
The gain shall be controlled via the 3-wire bus. Data bits D0 through D5 set the
gain/attenuator level, with 111111 being the min attenuation setting, and 000101 being the
max attenuation setting. A new gain/attenuator setting can be loaded while the VGA is on
(transmit-enable), but shall not take effect until transmit-enable transitions from LOW to
HIGH.

With every increment of the gain setting between 000110 (6) and 111111 (63) the typical gain will increase
accordingly.
8.2.3 Output stage current setting
The current (of the output stage) shall be controlled via the 3-wire bus. Data bits D6 and
D7 set the current. Setting 11 will set the maximum current for maximum linearity. The
current can be lowered for improved efficiency at lower output power levels, or lower
linearity requirements. Setting 00 will set the minimum current. A new current setting can
be loaded while the VGA is on (transmit-enable), but shall not take effect until
transmit-enable transitions from LOW to HIGH.

13. Application information
13.1 External components
Matching the balanced output of the chip to a single-ended 75 load is accomplished
using a 1 : 1 ratio transformer. For measurements in a 50 system R7 and R8 are added
for impedance transformation from 75 to 50 . R7 and R8 are not required in the final
application.
The transformer also cancels even mode distortion products and common mode signals,
such as the voltage transients that occur while enabling and disabling the amplifiers.
External capacitors are needed for the functionality of the circuit, the pins are internal
nodes in the output amplifier.
