General Description
The SY88149HL is a high-sensitivity, burst-mode capable
limiting post amplifier designed for Optical Line Terminal
(OLT) receiver applications. The SY88149HL satisfies the
strict timing restrictions of the GPON standards by
providing ultra-fast Loss-of-Signal (LOS) or Signal-Detect
(SD) output. Auto Reset and Manual Reset options are
provided to control LOS/SD output timing. For increased
flexibility, this device also includes an option to select
between LOS or SD output. The device can be connected
to burst-mode capable transimpedance amplifiers (TIAs)
using AC or DC coupling.
The SY88149HL generates a high-gain LOS or SD LVTTL
output. A programmable LOS/SD level pin (LOS/SDLVL)
sets the sensitivity of the input amplitude detection. This
device also offers the option to choose between a Loss-of-
Signal (LOS) and a Signal-Detect (SD) output from the
LOS/SD pin based the LOS/SDSEL pin setting. To select
SD output, leave LOS/SDSEL pin open or connect to Vcc;
to select LOS output, tie LOS/SDSEL-to-ground. If the
input signal amplitude falls below the threshold set by
LOS/SDLVL, LOS will assert high (or SD will de-assert low).
Once the input signal rises above the threshold set by
LOS/SDLVL, LOS will de-assert low (or SD output will
assert high). The SY88149HL also features a JAM function
which, when active, disables the LVPECL outputs. JAM is
active LOW when SD is selected and active HIGH when
LOS is selected. The LOS/SD output should be fed back to
the JAM input to maintain output stability under an invalid
signal condition. Typically, 3dB SD hysteresis is provided
to prevent chattering.
The SY88149HL operates from a single +3.3V power
supply over temperatures ranging from –40
oC to +85oC.
With its wide bandwidth and high gain, signals up to
1.25Gbps and as small as 4mVpp can be amplified to
drive devices with LVPECL inputs.
