JUMPER DESCRIPTIONS
NOTE
When a jumper is referenced as J#, where # is a number: A populated jumper en-
ables the function, an unpopulated jumper disables the function.
When a jumper is referenced as J#@, where # is a number and @ is a letter: Only
one jumper may be populated for each given # location. For example, populate J2A
or
J2B, not J2A
and
J2B.
J1:
BCLK SELECT
J1 selects the BCLK frequency. A choice of seven frequencies is available — these are from
64 kHz to 4.096 MHz.
J2A: FSYNC = 8 kHz
J2A sets the FSYNC to 8 kHz.
J2B: FSYNC = 16 kHz
J2B sets the FSYNC to 16 kHz, for use with the MC145482 only.
J3:
SIDETONE
J3 enables the sidetone path on the PCM Codec–Filter.
J4:
VAG CAP ENABLE
J4 enables the VAG filter cap. This jumper should be populated only when evaluating the
MC145481, MC145482, MC145483, and MC145484. It should
not
be populated when eva-
luating the MC14LC5480.
J5A: SPKR+ = RO+
J5A connects the path from the MC14LC5480 Pin 1 (RO+) to the RJ11 and handset. This
jumper should
not
be populated when evaluating the MC145481, MC145482, MC145483,
and MC145484.
J5B: SPKR+ = PO–
J5B connects a path from the PCM Codec–Filter Pin 4 (PO–) to the RJ11 and handset.
J6:
NOT AVAILABLE
J7A: MCLK = 256 kHz
J7A sets the MCLK Pin 11 to 256 kHz.
J7B: MCLK = BCLK
J7B sets the MCLK Pin 11 to be equal to BCLK.
