The LT?5554 is a 7-bit digitally controlled programmable gain (PG) amplifi er with 16dB gain control range. It consists of a 50Ω input variable attenuator, followed by a high linearity variable transconductance amplifi er. The coarse 4dB input attenuator step is implemented via 2-bits of digital control (PG5, PG6). The fi ne transconductance amplifi er 0.125dB step within 3.875dB gain control range is set via 5-bits digital control (PG0 to PG4). The LT5554 gain control inputs (PGx) and the STROBE input can be directly coupled to TTL or ECL drivers. The seven parallel gain control inputs time skew can be eliminated by using the STROBE input positive transition.
