General Description
The EL1881C video sync separator is manufactured using Elantec’s
high performance analog CMOS process. This device extracts sync
timing information from both standard and non-standard video input.
It provides composite sync, vertical sync, burst/back porch timing and
odd/even field detection. Fixed 70mV sync tip slicing provides sync
edge detection when the video input level is between 0.5 Vp-p and 2
Vp-p (sync tip amplitude 143 mV to 572 mV). A single external resis-
tor sets all internal timing to adjust for various video standards. The
composite sync output follows video in sync pulses, and a vertical
sync pulse is output on the rising edge of the first vertical serration fol-
lowing the vertical pre-equalizing string. For non-standard vertical
inputs, a default vertical pulse is output when the vertical signal stays
low for longer than the vertical sync default delay time. The odd/even
output indicates field polarity detected during the vertical blanking
interval. The EL1881C is plug-in compatible with the industry stan-
dard LM1881 and can be substituted for that part in 5V applications
with lower required supply current.
