| PGAB5 & PGAL5 Series for FDI VME Boards 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). Features/Benefits: * 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. * Phase match down to 1.0 with gain accuracy of 0.1 dB provides precision performance solutions to design engineers, system integrators and OEM's. * Butterworth or Bessel transfer functions with a broad range of corner frequencies are offered to meet a wide range of applications. Filter/Amplifier Options: VM32PAFF-PGAB5-100 3-pole Butterworth, 100 Hz to 100 kHz -12 dB to +60 dB gain in 6 dB steps VM32PAFF-PGAB5-300 3-pole Butterworth, 100 Hz to 300 kHz -12 dB to +42 dB gain in 6 dB steps VM2.0PAFF-PGAB5-2.0 4-pole Butterworth, >100 kHz to 2.0 MHz -12 dB to +36 dB gain in 6 dB steps VM32PAFF-PGAL5-100 3-pole Bessel, 100 Hz to 100 kHz -12 dB to +60 dB gain in 6 dB steps VM32PAFF-PGAL5-300 3-pole Bessel, 100 Hz to 300 kHz -12 dB to +42 dB gain in 6 dB steps VM2.0PAFF-PGAL5-2.0 4-pole Bessel, >100 kHz to 2.0 MHz -12 dB to +36 dB gain in 6 dB steps 70 60 Fixed Frequency Filters with Programmable Amplifiers PGAB5-100 & PGAL5-100 Frequency Response 50 Gain (dB) 40 30 20 10 0 -10 -20 10 100 1000 10000 100000 Frequency (Hz) Common Mode Rejection Ratio 0 -20 CMRR (dB) -40 -60 -80 -100 -120 10 100 1000 10000 100000 Frequency (Hz) Noise -60 -70 RTI Noise density (dBVrms/Hz) -80 -90 -100 -110 -120 -130 -140 -150 -160 -12 0 12 24 36 48 60 Gain (dB) Measured at 51.2 kHz 25 Locust St, Haverhill, Massachusetts 01830 * Tel: 800/252-7074, 978/374-0761 * FAX: 978/521-1839 e-mail: sales@freqdev.com * Web Address: http://www.freqdev.com PGAB5 & PGAL5 Series for FDI VME Boards PGAB5-300 & PGAL5-300 Frequency Response 50 40 40 30 30 Fixed Frequency Filters with Programmable Amplifiers PGAB5-2.0 & PGAL5-2.0 Frequency Response Gain (dB) Gain (dB) 20 20 10 10 0 0 -10 -10 -20 100 10 100 1000 10000 100000 -20 1000 10000 100000 1000000 Frequency (Hz) Frequency (Hz) Common Mode Rejection Ratio 0 0 -10 -20 -20 -30 -40 -50 -60 -70 -80 -100 -90 -120 10 100 1000 10000 100000 -100 100 Common Mode Rejection Ratio CMRR (dB) -40 -60 -80 CMRR (dB) 1000 10000 100000 1000000 10000000 Frequency (Hz) Frequency (Hz) Noise -60 -70 -60 Noise RTI Noise density (dBVrms/Hz) -80 -90 -100 -110 -120 -130 -140 -150 -160 -12 0 12 24 36 48 RTI Noise density (dBVrmsHz) -80 -100 -120 -140 -160 -180 -12 0 12 24 36 Gain (dB) Measured at 51.2 kHz Gain (dB) Measured at 51.2 kHz 2 25 Locust St, Haverhill, Massachusetts 01830 * Tel: 800/252-7074, 978/374-0761 * FAX: 978/521-1839 e-mail: sales@freqdev.com * Web Address: http://www.freqdev.com PGAL5 Series Specification (25C and rated power input) VME Board PGAB5-100 Analog Input Impedance Linear Input Range CMRR Maximum Input Range AC Couple (Optional Fixed Freq.)
