Description

Ground for signal detector.

Connect to VEER3 through a

external resistor determine

signal detect hysteresis width

(∆P).

When connect to VEER3 directly.

∆P ≈ 6dB (Typ.)

When 8.2kΩ is inserted.

∆P ≈ 3dB (Typ.)

Connect to VCCR2 through a

external resistor to decrease

signal detect level (SDL). When

open, SDL sets to 20mVp-p.

(single-ended)

Positive supply for signal

detector.

Positive supply for post amplifier.
