The digital servo loop measures the time difference between
input and output sample rates within 5 ps. This is necessary in
order to select the correct polyphase filter coefficient The digital
servo loop has excellent jitter rejection for both input and out-
put sample rates as well as the master clock. The jitter rejection
begins at less than 1 Hz. This requires a long settling time
whenever
RESET
is deasserted or when the input or output
sample rate changes. To reduce the settling time, upon deasser-
tion of
RESET
or a change in a sample rate, the digital servo loop
enters the fast settling mode. When the digital servo loop has
adequately settled in the fast mode, it switches into the normal
or slow settling mode and continues to settle until the time
difference measurement between input and output sample
rates is within 5 ps. During fast mode, the MUTE_OUT signal
is asserted high. Normally, the MUTE_OUT is connected to the
MUTE_IN pin. The MUTE_IN signal is used to softly mute
the AD1895 upon assertion and softly unmute the AD1895
when it is deasserted.
The sample rate converter of the AD1895 can be bypassed
altogether using the bypass mode. In bypass mode, the AD1895’s
serial input data is directly passed to the serial output port with-
out any dithering. This is useful for passing through nonaudio
data or when the input and output sample rates are synchronous
to one another and the sample rate ratio is exactly 1 to 1.
The AD1895 is a 3.3 V, 5 V input tolerant part and is available
in a 28-lead SSOP SMD package. The AD1895 is 5 V input-
tolerant only when the VDD_IO supply pin is supplied with 5 V.
