DESCRIPTION
The SA5214 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 SA5214 can be DC coupled with the
previous transimpedance stage using SA5210, SA5211 or SA5212
transimpedance amplifiers. 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 noise filtering, adjustable
input thresholds and hysteresis. The threshold capability allows the
user to maximize signal-to-noise ratio, insuring a low Bit Error Rate
(BER). An Auto-Zero loop can be used to minimize the number of
external coupling capacitors to one. A signal absent flag indicates
when signals are below threshold. Additionally, the low signal
condition forces the overall TTL output to a logical Low level. User
interaction with this “jamming” system is available. The SA5214 is
packaged in a standard 20-pin surface-mount package and typically
consumes 42mA from a standard 5V supply. The SA5214 is
designed as a companion to the SA5211/5212 transimpedance
amplifiers. These differential preamplifiers may be directly coupled
to the post-amplifier inputs. The SA5212/5214 or SA5211/5214
combinations convert nanoamps of photodetector current into
standard digital TTL levels.
