DESCRIPTION
The SA5217 is a 75MHz postamplifier system designed to accept
low level high-speed signals. These signals are converted into a
TTL level at the output. The SA5217 can be DC coupled with the
previous transimpedance stage using SA5210, SA5211 or SA5212A
transimpedance amplifiers. The main difference between the
SA5217 and the SA5214 is that the SA5217 does not make the
output of A1 and input of A2 accessible; instead, it brings out the
output of A2 and the input of A8 thus activating the on-chip Schmitt
trigger function by connecting two external capacitors. The result is
that a much longer string of 1s and 0s, in the bit stream, can be
tolerated. This ”system on a chip” features an auto-zeroed first
stage with noise shaping, a symmetrical limiting second stage, and a
matched rise/fall time TTL output buffer. The system is
user-configurable to provide adjustable input threshold and
hysteresis. The threshold capability allows the user to maximize
signal-to-noise ratio, thereby insuring a low Bit Error Rate (BER).
An auto-zero loop can be used to replace two input coupling
capacitors with a single Auto Zero (AZ) capacitor. A signal absent
flag indicates when signals are below threshold. The low signal
condition forces the TTL output to the last logic state. User
interaction with this ”jamming” system is available. The SA5217 is
packaged in a standard 20-pin surface-mount package and typically
consumes 40mA from a standard 5V supply. The SA5217 is
designed as a companion to the SA5211/5212A and SA5210
transimpedance amplifiers. These differential preamplifiers may be
directly coupled to the postamplifier inputs. The SA5210/5217,
SA5211/5217 or SA5212A/5217 combinations convert nanoamps of
photodetector current into standard digital TTL levels.
