Notes to the characteristics
1. The oscillator is designed to operate together with Murata resonator CSB503F58 or CSB503JF958 as SMD. Change
of the resonator supplier is possible, but the resonator specication must be close to the specied ones.
2. The AVL input voltage is internal. It corresponds to the output voltage OUTL and OUTR at AVL off.
3. The listed pin voltage corresponds with typical gain steps of +6 dB, +3 dB, 0 dB,
6 dB and 15 dB.
4. Attack time constant = CCAV × Ratt.
5.
Example: CCAV = 4.7 F; Idec =2 A; G1 = 9 dB; G2 =+6dB → decay time results in 4.14 s.
6. When reset is active the GMU bit (mute) is set and the I2C-bus receiver is in the reset position.
7. The AC characteristics are in accordance with the I2C-bus specification for standard mode (clock frequency
maximum 100 kHz). A higher frequency, up to 280 kHz, can be used if all clock and data times are interpolated
between standard mode (100 kHz) and fast mode (400 kHz) in accordance with the I2C-bus specification.
Information about the I2C-bus can be found in brochure
“I2C-bus and how to use it” (order number 9398 393 40011).
