PGAB5 & PGAL5 Series for FDI VME Boards Fixed Frequency Filters with Programmable Amplifiers Description The PGAB5 and PGAL5 Series of fixed frequency filters with programmable gain amplifiers utilize digitally controlled gain modules that were designed for Frequency Devices’ multi-channel VME board products to condition DC-coupled wide-band signals. Amplifiers are programmed by an 8-bit serial data stream for gain selection using clock, data and strobe inputs. Other standard performance features include differential input, single ended output, 5V interface logic and low noise/distortion. Available options include AC coupled input (all models) and/or differential output (VM32PAFF only). PGAB5-100 & PGAL5-100 Features/Benefits: • Phase match down to 1.0º with gain accuracy of 0.1 dB provides precision performance solutions to design engineers, system integrators and OEM’s. Frequency Response 70 60 50 Gain (dB) • Offers a low cost, versatile and convenient way to provide up to 32 channels of precision filtering and amplification in a single width B-size (6U) VME form factor. 40 30 20 10 0 -10 -20 10 100 1000 10000 100000 Frequency (Hz) Common Mode Rejection Ratio 0 CMRR (dB) -20 -40 -60 -80 -100 -120 10 100 1000 10000 100000 Frequency (Hz) Noise -60 -70 RTI Noise density (dBVrms/√Hz) • Butterworth or Bessel transfer functions with a broad range of corner frequencies are offered to meet a wide range of applications.
