IDT claims that the 6bit F1912 and 7bit F1956 DSAs reduce transient 'glitches' during most significant bit (MSB) transitions by up to 95%. Glitch-free response enables customers to simplify their software interface, improve reliability, prevent damage to expensive sub-assemblies such as power amplifiers, and limit over-ranging of data converter inputs.
The F1912 is available in a 4 x 4mm 20 pin QFN package and the F1956 is supplied in a 5 x 5mm package. Both feature 50O impedances for ease of integration.
The F2250 VVA features a frequency range of 50 to 6000MHz, an insertion loss of 1.4dB at 2GHz, IP3I linearity of 65dBm and operates in a temperature range between -40 and 105°C. It requires a single positive supply voltage of 3.15 to 5.25V with a control range from 0 to 2.8V, using either positive or negative voltage slope.
