Notes: 13. External loading capacitors are required to allow the crystal to oscillate. Maximum crystal frequency
is 8.0 MHz in FRN mode (100 kHz sample rate).
14. With a 8 MHz crystal, two 10 pF loading capacitors and a 10 M
parallel resistor (see Figure 8).
15. These times are for FRN mode.
16. SSH only works correctly if HOLD falling edge is within +15 to +30 ns of CH1/2 edge or if CH1/2 edge
occurs after HOLD rises to 64 tclk after HOLD has fallen. These times are for PDT and RBT modes.
17. When HOLD goes low, the analog sample is captured immediately. To start conversion, HOLD must
be latched by a falling edge of CLKIN. Conversion will begin on the next rising edge of CLKIN after
HOLD is latched. If HOLD is operated synchronous to CLKIN, the HOLD pulse width may be as
narrow as 150 ns for all CLKIN frequencies if CLKIN falls 95 ns after HOLD falls. This
ensures that the HOLD pulse will meet the minimum specification for thcf.
