DESCRIPTION
The SY100EL17V is a quad differential receiver. The
device is functionally equivalent to the E116 device with the
capability of operation from either a ECL supply voltage
(–3.3V or –5V) or PECL supply voltage (+3.3V or +5V).
The EL17V provides a V_BB output for either single-ended
use or as a DC bias for AC coupling to the device. The V_BB
pin should be used only as a bias for the EL17V as its
current sink/source capability is limited. Whenever used,
the V_BB pin should be bypassed to ground via a 0.01µf
capacitor.
Under open input conditions, the /D input will be biased
at V_CC/2 and the D input will be pulled down to V_EE. This
operation will force the Q output LOW and ensure stability.
