Analog CATV Transimpedance Amplifier
General Description
The MAX3660 high-linearity analog RF transimpedance
amplifier (TIA) is intended for passive optical network
(PON) video receiver applications. With 66dBΩ maxi-
mum variable gain and integrated uptilt, the MAX3660
provides 23dBmV/channel ±1dB at 870MHz
(19dBmV/channel at 47MHz) for optical inputs between
+2dBm to -8dBm (at 4.2% OMI) using simple feed-for-
ward automatic gain control (AGC). It can also be config-
ured with feedback AGC for even greater dynamic
range. CNR is better than 48dB from 47MHz to 870MHz
(1.0A/W photodiode and -165dB/Hz RIN) at -8dBm with
4.2% OMI, or -6dBm with 3.3% OMI. CSO and CTB are
better than -61dBc and -65dBc, respectively. The device
supports extended frequency operation to > 1000MHz.
The very low true-TIA input impedance accommodates
a variety of photodiodes, eliminating the need for an
input matching network and improving yield.
