NPC SM5837AF Datasheet
SM5837AF
NIPPON PRECISION CIRCUITS INC.
OVERVIEW
The SM5837AF is a variable-length delay line LSI.
It has 12-bit input/output signal which can be set to
undergo a delay in the range of 31 to 2078 delay bits.
Maximum operating frequency is 40 MHz, making it
ideal for use in video signal processing applications.
