M02040G-14

M02040-14 3.3V Limiting Amplifier for Applications to 2.125 Gbps The M02040-14 is an integrated high-gain limiting amplifier. Featuring PECL outputs, the M02040-14 is useable in applications to 2.125 Gbps. Full output swing is achieved even at minimum input sensitivity. The M02040-14 oper- ates with a 3.3V supply. DC_Servo supports applications requiring instantaneous output response. The M02040-14 also includes two analog RSSI outputs proportional to either the average or peak to peak input sig- nal and a programmable signal-level detector allowing the user to set thresholds at which the logic outputs are enabled.

Revision History ASIC Revision Level Date Description Revision H Final December 2005 -14 Clarify comments on the use of the DC_Servo pin in the pin definitions and applications information. G Final August 2005 -14 Correct Jam connection in block diagram and typical applications figures. Correct I figure (reference current generation). REF F Final June 2005 -14 In the DC specifications, update R DIFF and RSSIavg; added note 1; moved IN RSSIavg from ac specifications. In the ac specifications update V , V , IN(MIN) LOS DJ and tr/tf; add specifications for LOS assert and deassert. Updated R ST values and the typical LOS curve (Figure 4-3 - Figure 4-5). Added typical hysteresis curve (Figure 4-6). E Preliminary March 2005 -14 Update the DC specification V . Update the ac specifications V , v , OH IN(MIN) n T , and T . Corrected the EVM ordering number. LOS_ON LOS_OFF D Preliminary December 2004 -14 Update the DC specifications R DIFF and V . Update R values, update IN IH ST RSSI information. Remove peaking circuit applications information as this is not necessary for the -14 revision. Note that the -14 is for 3.3V only.
