BH2615S
Electronic tuning PLL frequency synthesizer
BH2615S
The BH2615S is a PLL frequency synthesizer, featuring low radiation and low power consumption.
It includes high sensitive RF amplifier and supports IF count function.
zFeatures
1) Low voltage operation (2.7V~)
2) High speed prescaler capable of direct dividing VCO (130MHZ) frequency.
3) Low radiation (Xtal OSC 75kHZ)
4) Low supply current (PLL ON:5mA, PLL OFF:300µA, Typ. VDD=3.0V).
5) Reference frequency : 25, 12.5, 6.25, 3.125, 5, 3, 1kHZ
6) On chip IF frequency counter.
7) Unlock detector
8) Output port : 7 ports (open drain output)
9) Data input : serial input (CE. CK. DA)
