Description
The SP8782 is a multi-modulus divider which divides by 16/
17 when the Ratio Select input is low and by 32/33 when
theRatio Select input is high. When high, the modulus Control
input selects the lower division ratio (16 or 32) and the higher
ratio (17 or 33) when it is low.
The device uses resynchronisation techniques to reduce the
effects of propagation delays in frequency synthesis.
The SP8782A (ceramic DIL package) is characterised over
the full military temperature range of -55°C to +125°C, the
SP8782B (miniature plastic DIL package) over the industrial
range of -40°C to+85°C.
